I just recently got a ZOTAC GTX 660 (2gb) and am getting a low FPS in games I should be EASILY able to max out. And it seems like even if I lower the video settings to the minimum my FPS doesn't even rise more than 5 FPS.. so I'm thinking my CPU is possibly bottle-necking my GPU?
The CPU is responsible for producing the information for the frames. The GPU is responsible for rendering the frames. If you lower the video settings and see an increase in frame rate, then the video card is suffering. If you increase the video settings and the frame rate stays the same, then the CPU is suffering. Every game is different regarding how the CPU and GPU are utilized.
I'm not sure if this is true but I read this on Steam's forums somewhere. If that is true then I'd definitely say it is a bottleneck because I seem to have the issue mentioned above! ^^
I'm suggesting switching to Intel, but the I would have to also buy a new motherboard and buying a new high-end CPU AND motherboard could be quite pricey. I don't have much money so do you guys suggest I get a Intel Mobo + CPU or is there any good AMD (am3) CPUs that could get the job done w/ my 660?
Yea I think Sumuk has a good build idea there with just really changing out your processor and your motherboard. You could always upgrade your ram at a later point 8 gigs to get more of a optimal experience out of that. You can't overclock but games aren't really swayed much in terms of cpu performance with i5/i7's gen 2 sandy, or gen 3 ivy.
