i hate when people bring out the whole, amd for games, intel for multi-tasking. First off, there are more then a fare share of intel processors that can do gaming well. And there are more then a fare share of amd processors that can multitask well.
Personally i use AMD, mainly because of there price, and i think the colours of their boxes kicks the s**t outta the intel colours :P.
All comes down to personal prefference really :P. And theres a whole section for amd vs. intel
. I also think right now that in the technology race although INTEL has there extreme edition, AMD has beat INTEL to practical 64 bit processors for the average consumer by a mile. So i think that gives them a slight advantage for the future.
