bad cpu?

[ginge51]

hi all

ive noticed when i use 1 core on this 4400 x2 cpu instead of 2 cores i get vertually no performance gains whatsoever?
so when i switch on both cores again when playing games etc i get maybe 2-3 fps increase
any1 else get this problem or do i have a duff cpu?

thx

I would guess that the software you're not seeing any difference with is only single-threaded, so it will only ever use one core.

the game i tryed it with was colin macrae dirt i think this is optimised for dual core?
