I'm looking for a new base unit to replace my very old, slow present one. On reading many articles I'm looking at having the AMD 64bit CPU, prob the 3000+ or 3200+. I've had various quotes from manufacturers, with my favourite up to now only having motherboards that support socket 754, they do one that supports both (ASRock K8 Combo) but it only has a maximum of 2GB RAM. I'm not technically minded at all, it's just what I've been reading. Apparently the socket 754 is not going to be supported much longer and I want a system that I can upgrade in the future. Any advice or opinions much appreciated.
