I would be grateful for some advice here - I mainly use my computer for Battlefield 2 plus some video encoding and general web surfing. Currently I've got: Opteron 146 oc to 2.95ghz on air. DFI nf4 lanparty 2gb ram x1900xtx WD Caviar 200gig PATA hard drive I quite fancy getting a dual core cpu to try and overclock. I can only afford a x2 3800+ though, which in all probability won't clock to the same level as the opteron (unless I get really lucky). Therefore, would changing the opteron for a lower clocked dual core cpu make much difference to gaming speed and general windows usage, or would I be better off going for a 150gig Raptor hard drive which should improve the boot time and loading times? Cheers.
