Is my CPU good to support my gaming card.

There will be a bottleneck from the CPU how bad depends what resolution you are gaming at. Overclocking will reduce the bottle neck and buying an i5 2500K (or even a 760 or 2300) will remove it totally.

yeah i hav already installed card and i had played some games .Call of duty black ops was stucking a bit then i changed my psu i have corsair hx1000w now and if i increase the resolution of game the graphic started to stuck . also noticed that cpu temp was also going high . i usually notice temp like 39c or 40c now when i was playing game at 1920x1080 the cpu temp was 45c i think that my cpu can not process faster to support gtx 560ti .
now i think that my cpu is getting hammered by gtx560 because i dont hav psu problem .its a newly bought hx1000w
what should i do now . should i overclock . tell me how to do it as im new to overclocking . which software i would need and tell me precautions as well.

is it good cooler for overclocking?

my pc specs are
core 2 duo e8400
XFX 750i sli motherboard
corsair xm2 2gbx2
gtx 560ti

yeah rams r ddr2 800mhz .

Well, since you're short of cash, it makes the most sense to see what overclocking will gain you. The E8400 is great for overclocking, and will give you good fps increases since the CPU is the bottleneck in the system.

If you find that overclocking the CPU doesn't give you as much as you want, well, then it's time to start saving your cash. If you go the upgrade route, switch both the motherboard and CPU. the 2500k is an excellent processor for the price...

how to check FPS

also tell me will my current processor permanently decrease gtx560 performance . i had stoped gaming when i come to know that cpu is bottleneck for graphic card .

so what should i do . should i replace my processor with CORE 2 QUAD or just go for
CORE i5 2500k or core i7 2600k .

will it handle gtx 560 in sli ?
