What would be better a A64 X2 4400 1mb p/c or a Pentium4 840 1mb p/c? and why? A mate is wanting a system for Folding and playing the occational game. Best air cooling solution for recomended system, sound is not a huge issue as it will be kept in a study. Feel free to move this to CPU's if you think it better placed there, i feel it's not.
