cpu is um intel i7 920
psu, not sure what that is.... =/
I've kinda gotta find out what your PSU is now, brand, model and wattage.
Also if your CPU is overclocked / what clock speed is it running at / how many PCI-E slots you have on your motherboard at what bandwidth etc.
Sorry, but this is just to ensure nothing stuffs up.
... but mine is a 550 ti top, theres a difference :3 (there is a difference, right?)
Better cooler and overclocked.
