hi,
im kinda noob here.so here's a noob question.
i currently have i5 760(stock fan) and sapphire 6850.after playing bf3 i realized my rig just suck.so, im wondering if i spend 400$ on a gtx 670, would my cpu bottleneck the performance of gtx 670. i've read some review about cpu playing an important role on fps(shogun 2),but at the same time there are article saying that cpu didnt even matter when playing on 1920-1080 res(1% difference between i5 760 and SB).im not sure which article is accurate/true.
-is there any truth to these article?need help from experienced user.
-should i switch to sandy bridge or just go ahead with gtx670 and my i5-760 ?
-if switch, should i wait for the new architecture from intel coming out in several month or just buy SB(2500K)?

some of my friend keep suggesting me to get IB,but most review suggest heating problem and thermal throttling,any opinion?and yes,finance is also a concern but not that much.

A i5 760 is perfectly fine...don't worry...it can happily handle the 670:) 

I suggest you wait for the next generation of CPU's after IB if you want to upgrade:)

i totally agree, wait for the 4000 series. its gonna be an architecture redesign rather than a die shrink. so expect it to be noticeably faster instead of the last two generations that were just barely faster, albeit for less money.

i forgot to mention that sometime while gaming ,i notice a slight frame freeze while playing BF3.Is this from cpu or GPU?

Probably the GPU that's causing the odd lag, the 6850 is going to struggle with BF3 at 1080p if you are trying to do ultra settings.

As said above, there isn't much point in upgrading from a first gen i5 right now, Sandy/Ivy is better, but not enough to justify spending money on a new motherboard and CPU, especially if all you do is gaming. In any case, the i5 760 won't hold back any single GPU setup right now, so go for the 670 if you are really itching to upgrade, that will significantly help your BF3 performance.

any benchmark or article that might support your claim .i tried google but no such benchmark that use 1920x1080 res.mybe my googling skill is still green,so if you have any extensive data regarding this matter,wold be greatly appreciated.

Here is a link to a CPU benchmark for BF3. The i5 760 is not on this list, but the i5 750 is it's clocked at 2.66GHz rather than 2.8GHz. The difference between the i5 750 and the i5 2500k at 1920x1200 resolution is a whopping 2FPS with a GTX 580, and that difference is only on the minimum framerates, not the maximum. 2 FPS, or probably a bit less than that as the 760 is clocked a bit faster is not a major difference that justifies upgrading the CPU. Here is an article benchmarking framerates on DX11 GPUs for BF3 on ultra at 1920x1200. The 6850 averages 22FPS, unplayable. That benchmark indicates you need a 6950 or 560Ti to do ultra, and that's only if you are happy with 30FPS. Granted 1920x1080 has a few less pixels, so the 6850 might do a little bit better, but still not enough for a smooth experience. BF3 is very much a GPU bound game, as long as you have a decently fast quad core, which you have, you are fine with for the CPU, the game just needs a very powerful graphics card for optimal performance.

Hello all,with an i5-2500k and HD 6850 @ 1680x1050,would i be able to play Battlefield 3 on let's say,Medium - Highish with stable 50-60fps?
