hey I just noticed that card's length isnt too long a la 8800GTX/Ultra.
Its gonna be a power hungry monster tho...make sure your PSUs can keep up.
while nVidias high-specs are nice, I think the power/performance mid range value is where ATI shines.
If I didn't already own a 8800GTS512MB, I would probably buy a HD48x0 card.
crappy old school NES games are more entertaining than next-gen games.
