Ok,

Almost time for some component upgrade.

I am stuck between a sandy bridge and the ivy bridge, i5 and i7,

Whats the best bang for the buck for FSX, is it still the 2500k?

Wondering this very much myself as well.

Two primary dilemma's from my point of view:
1) Sandy bridge or Ivy bridge. If the overclocking of the IB has become worse compared to SB, how much is that affected to your FSX performance. Even with lower over clock, is the IB still faster, or is SB better performing because of higher over clock in the end?

2) Secondly, i2500k/i3570k or i2700k/i3770k. (co-depending on the outcome of my first point)
I'm thinking i2500k or i3570k are fine choices. If I'm correctly informed, the i3570 is basically the successor of the i2500k?
Or are there clear advantages of the i2700k/i3770k which might justify the roughly 100extra euros?
Apart from SB or IB, what are your experiences and/or noticeable differences between the 'lower-end' i2500k/i3570k, and the 'higher-end' i2700k/i3770k?

Opinions please :)

Not sure what choice to make regarding any upgrade, but I'm currently running a 2700K at stock speed and it runs FSX very nicely. I will try an overclock some time, but I think I'm actually quite happy the way it is now. At some busy airports I could use a little more power, but other than that, no complaints :-)

I still think the i5 2500K is the best value. Yes, you might get a few hundred more MHz out of the 2700K, but you're paying a premium for that and it's probably not going to be that much of a difference in terms of framerate. You have to turn the hyperthreading off to get the really high overclocks on it anyway, which effectively makes it an i5.

I would not buy Ivy Bridge for an FSX system, it doesn't overclock as well and I think it's a much lower value proposition.

I agree with Ryan completely. I recently upgraded my motherboard, RAM, and CPU to have an i5 2500k to replace my i7-950. The 2500k only cost me $150, and while running a Corsair H50 cooler (out of production, but lowest model of liquid cooler from Corsair) I have it overclocked to 4.5ghz with no stability issues. I also believe the i5 will give off slightly less heat, jsut because the nature of a smaller chip, making your cooler more effective. The 2500k is a better value than the 2700k at this point.

I did exactly the same thing. Sold my i7-950 on ebay and bought i5 2550k as it was on sale and reduced to £20 cheaper than the 2500k! Running it at stock 3.4 ghz at the moment as it runs what I want it to very well. I will overclock maybe later in the year when the system has run itself in.
The money I saved from getting the 2700k I bought the Corsair H80 watercooler and a Coolermaster case which are very good. Keeps my temps at 23c at idle and around 38c when running FSX.

Alex, since you are in the uk take a look at this, I just bought one to upgrade my second machine.

Hey dude,

The thing about this is it supplies two components I already own, so for me, I will buy seperately. I assume the z77 asus boards are the besT?

I don't know how is i5, I have i7 2700K and like harvester21 allready said - I am very happy at stock speed. In this moment, CPU works at 4018MHz (stock speed) becouse of mainboard i guess.
I'll do some overclock, probably to 4.8GHz, but I'd like to know how will this improve FSX performance. My only problem is at very busy airports, FPS are going down to 20 and I have some stutters. In general, FPS is above 30(about 50fps most of time, and goes to 100fps in the air)without stutters. They appears about 20 fps in my case.

i5 is probably the best value for mooney because half the price of 2700K.

I would appreciate If someone can tell me - should I overclock CPU to 4.8GHz? Whether this will improve the FPS and performance so much?

Thanks

You should really ask in a different thread, but yes, overclocking will lead to higher frames.

should I overclock CPU to 4.8GHz?

Hi Zeljko, given your other questions and comments, I doubt very much if you should attempt such a drastic overclock. 4.8GHz really is expert level. If you are hapy with what you have, leave it alone. If you want to explore the potential of your hardware, you will need to start by researching the various overclocking forums available to find one that suits you.

To put it bluntly, Intel dropped the ball with Ivy Bridge. They used mundane thermal paste instead of a fluxless solder when binding the integrated heat spreader to the CPU itself. Not only does this result in inferior cooling performance, but it calls into question the longevity of the CPU itself, since thermal paste can theoretically degrade over time (takes a few years, granted), and replacing the IHS isn't exactly a common task. The only reasonable explanation is that they did this to lower production costs, though those savings were obviously never passed onto us.

Because it runs very high temperatures with an aggressive overclock (despite the reduced power consumption and TDP), Ivy Bridge is widely regarded as a failure in the overclocking community. Since overclocking gives such great results in FSX, you should probably stick to Sandy Bridge.

I had to make this very decision two weeks ago when I upgraded my own machine, and went with an i5 2500k. The 2700k is supposedly capable of better absolute overclocks (though clock for clock with HT disabled, it's really no faster than the 2500K), but it's ~33% more expensive, I only spend about a fifth of my gaming time in FSX, and I figured I'd pick up a Track IR, some new pedals, or another SSD with the difference. None of the Ivy Bridge processors were serious considerations given what I'd read around the enthusiast boards, though I did get a Z77 based motherboard just to have the option down the road.

And FWIW--I came from an i5 750 with a 3.8 GHz overclock. Was able to recycle both my RAM and my aftermarket CPU cooler with this build, which saved me a few bucks (first time ever!). You'll definitely be happy with a SB processor coming from an i7 930.

I just bought the i5 sandy also, for me the best value and performance you can get taking into account money,

hopefully I will see an improvement from my overclocked I7 930

I did that allready(OC forums), I have hardware for OC and I know how to do it. I choose 4.8GHz becouse 2700K is stable there. I only asked if it is worth to do that for FSX. Like I said, my only problem is in big and busy addon airports, and I don't know how big the difference will be after that - from 4GHz to 4.8GHz. 3, 5 10, 20fps?
Thank you Paul

Debatable at this point. The fast RAM on the market paired with IB really seems to benefit performance nearly as much as CPU clock speed for FSX. A 4.5GHZ IB with 2666MHZ RAM ~ 4.8GHZSB with 1866MHZ RAM

From just under a years experience with the SB i5 2500K and a reasonable Corsair H70 water cooler, I can't recommend it enough. My rig was built for FSX, I try to keep little else on it. I have a very simple OC to 4GHz coupled to a 3-4 years old graphic card, proving its certainly the processor that has the FSX oomph. FSX and the NGX are very smooth, no major stutters even with high AI traffic and moderately graphically demanding airports. I don't watch the frame rates, you can get obsessed with that. Just look out the window and see how immersed you feel. Hope your i5 gives you as much simming enhancement as mine did.

Not strictly correct. Some 2700k can reach and maintain a stable 4.8 and some will burn out at that level. That is what makes it an experts level. I suggest aiming for 4.4 or 4.6 and enjoy what you get.

I only asked if it is worth to do that for FSX. Like I said, my only problem is in big and busy addon airports, and I don't know how big the difference will be after that - from 4GHz to 4.8GHz. 3, 5 10, 20fps?

You are adding 15~20% more processing power, so you should exect 15~20% better performance from CPU bottlenecked activities. If it is your CPU that is holding you up and not your graphics card, then if you currently get 20fps at 4GHz, you can expect 23 or 24fps at 4.8GHz. If you currently get 50fps, you can hope for almost 60. Of course, if you are externally limted to 30fps as recommended, then you wont see a change there, it will just be smoother.

This thread has been basicly about overclocking the IB vs. the SB.

I do not overclock and it is not something I want to do. Which would be better for us non-overclockers, the IB or SB? I am more interested in the best RAM, motherboard, and video card.

Hi guys,

If you're not going to be doing any overclocking and focus on buying the fastest CPU with fastest motherboard with the fastest memory combination, then from what I've read about Ivy Bridge, this would be our best option. The fastest Core i5 paired with a decent Z77 motherboard such as ASUS and 2333 memory should be good, but the fast memory will cost more, of course. Should be good for FSX, although overclosking is still the way to go in my opinion, but there does seem to be an issue with IB at the moment. Maybe Intel will fix this issue.

Im going with the IB and the http://www.inet.se/p...si-z77a-s01-atx motherboard. Im not going to OC at first, but maybe in the future.

What exactly is the problem with OC the http://www.inet.se/p...4ghz-ivy-bridge ?

Thx

Ivy was just made to have a higher energy saving compared to SB. Its just a little bit faster than SB not really something to talk about once you got a good OFC system like 4,8GHz on a I7 or 4,5 on a i5. You will battle Ivy on the knees!

Ive read somewhere the Ivy gets higher temperature?
