I've heard of bottle necking in video cards due to CPUs. My question is how do I know how far my CPU is compatible with what video cards.
CPU model: BX80637i53330
For instance, would 02G-P4-2684-KR work completely?
Yeah, that would work fine. I would look at getting a 7970 ghz though. Also could you please put the actual name in and not the model number. It makes it way way easier. There is no formula or anything on how to find which cpu will bottleneck. All you can really do is make an educated guess. But I a pretty sure any new i5 will not bottleneck any gpu on the market.
I would OC the cpu a little, but other than that yea its perfect, 7950, gtx 660ti, are decent cards for 300-400 dollars. Could probably also find two 7850s or 7870s for under 400 and surpass 7950 maybe even 7970. Just my 2 cents.
I myself think that your choice of graphics card is great. I'm not trying to offend anyone here but try to avoid people who tell you to go with a different brand and don't back it up with and facts or as to why you should. Here are some things to consider:
GTX 680 is the fastest single gpu video card out there (even faster than 7970)
HD 7970 typically offers more VRAM which translates to being able to perform higher at very high resolutions and very high graphic settings. (demanding games only)
Most games won't even reach 2gb VRAM even with high resolutions (i personally have EVGA gtx 680 2gb superclocked 2687 signature 2 and run 3 1920x1080 monitors)
so far i've only seem skyrim to max out the VRAM (at max settings) but i have yet to test battlefield 3 at surround (which is known for being very demanding)
for future proofing, 7970 is better as it provides more VRAM so you won't have to worry about getting bottlenecked in that area and can just crossfire for more performance in the future.
7970 does have more availability it seems to be cheaper.
