[CLN-list] A good PC hardware for CLN ?

Hi ! I used CLN lib on linux debian Woody and try now libcln3 on debian Sarge ( on a Athlon T-Bird 1GHz 400Mo RAM ). I think to buy a more recent PC computer. What kind of PC for CLN - processor INTEL or AMD - to execute speedly integer computations ? Is motherboard worthy ? Thank you for your help. Fabrice
