Which is better? Everyone's getting the core2duo, but the 775 form factor is quite old (q2 2005?) and the AM2 was q2 2006. Also, AM3 processors will be backwards compatible with the AM2 form factor. Although core4quads (if thats what they're called lol) are compatible with these motherboards, I expect most people's upgrade cycles will lag behind a bit?
I dunno, in my eyes, at the moment, although *currently* athlons are less powerful, you pay less as a consequence, but the 'building block' is newer, so if you want to play safe for the long term aren't they a better bet?
Sorry if I'm rambling... but I hope you get what I mean? I just built a core2duo and love it because there's nothing that can top it at the moment really, but if I think, maybe it would have been more sensible, moneywise at least, to go AM2?
