I did some (minor) poking around with wholesale a while back and the margins are jack, if you find different please let me know. Maybe on high end GPUs there are more savings than 5% on select OEM parts. I'd really like to know. I didn't talk to anyone and from stuff I've been picking up at work on importing, that's basically what you gotta do.
3x 7970's could be a good alternative, then get rid of Bulldozer and that mobo :lol
*3x 6990 would be faster from a pure computational power standpoint which is what I'm getting a vibe from. If it's gaming then 7970 for sure.
