Also at most, and I mean most I would sli 8800GTS, unless the GTX drops to like 200~300 price range, and I buy one, and then buy another couple weeks latre.
I really dont like the 6 12V rails layout. I mean, if just one of the rails is overloaded, the system just wouldnt work.
IMO, the single rail power supply is the only way forward. Thats the reason that im such a fan of PC P&C. I think that the PC P&C 750W is much better value than the cooler master.
