dual core is shit!
Why do you think it's shit...
It's much better than only a single core cpu...
Set your grafic card to Performance Mode, or even overclock it using RivaTuner... You could also overclock your pc, on bios.
overclock a lattop doesnt sound a good idea at all XD
I agree that overclock ain't a good idea, even if you wanted to oc your gpu just a bit, you won't see any difference until you get a better cpu or a gpu. (Especially if you want to oc some old crap
)
