I'm looking for something to keep me going 'till about christmas time/early next year. I know it's old but if I can squeeze say a 10% improvement out of it for only a few quid I might as well go for it. OK this is my current system spec: Abit NF7-S rev. 2 1gig DDR RAM @ 198 FSB (2 x 512mb dual channel) Athlon XP-Mobile 2400+ @ 2400MHz (1.85Volts) Nvidea 6800LE HSF/Cooler: Not sure. Think its Thermalright. Was popular when the XP-M's first came out. I think I've clocked the CPU as far as I can while remaining stable, though I can get it to 2500 but crashes often. Maybe its overheating. It runs at about 55-60 degrees when busy. So what would you do with this for a cheap upgrade (~£50). Maybe a second hand CPU? Not sure what the best chip is I can use.
