im Intel, but AMD rocks as well.. i recommend you buying an AMD, cause it's cheap and Intel is very expensive compared to AMD.
also, AMD specializes itself for games, Intel doesn't really.. if you wanna do videocapturing and -editing on your system.. don't buy an AMD processor, buy an Intel instead.. if you want to run games, i would say AMD..
don't go buy a 64-bit for alot more.. cause it's not really worth it.. if you got money buy yourself an Intel Dual Xeon or something..
the AMD Athlon XP/MP should do the job..
