hi. .. im thinking of this : ASUS M2NPV-VM 2*512 ram 533 athlon 64 3000+ OR athlon X2 3600+ (both am2) now the processor is worrying me how much is the difference between these two?? is there huge performance difference?? if i put a gud gfx card later, will the proccy matter?? ive read somwhere that if u put a gud gfx card, a athlon64 3000+ works good enough ... nd athlon 64 is almost half the price of X2 r the prices of X2 coming down ??? then i can change it to a better X2 later so... what should i do??
