hey i'm getting a new processor and my budget is £200, so i was wondering if i could get a 2600xp-m and overclock it or get a new athlon64 3000+ (newcastle) and a Abit NF8 Motherboard. Which should i do? the athlon 64 combo adds up to £171 and the xp-m is only £70. I dunno which would be a better performance? Help please.
