Being an Intel and ATI kinda guy, I'm sure the following system would create holy wars in some circles. Personally though... it is right up my alley. I'd love to build it... but is really crazy for someone who hasn't played a computer game in MONTHS and MONTHS... so instead I'll just DREAM about it. :)
