i have just upgraded to the 64 bit era with a AMD3500+ but have found that i would be better off with a 1mb L2 cache as the 3500 only has a 512k L2 cache so i am looking at getting another cpu but i cant make my mind up. i have looked at the amd x2 3800 but this only has a 512k cache also looked at the single core AMD 4000 with a 1mb cache also the single core 3700+ clawhammer these are within my price range but im not sure which one to go for.i have also looked at the AMD x2 4200 but this maybe slightly out of my price range. has anyone any suggestion.cheers
