Hey, I decided to go for a GTX 780 rather then a 680 now because I just get alot more bang for the buck. For only like 50 more I would be stupid not to choose the 780. I can live without the bootscreen for now, and only 2,5GT/s speeds in windows don't seem to be such a big deal neither. I found a first revision (A1) Nvidia reference model, will this work fine with 10.8.5? As far as I can tell it should, but I thought I'd ask you guys first, before wasting some money. Also, is 280 incl. shipping costs a ok deal or not so much? Maybe one last question about powering the beast: I'm planning on using a 2x6 pin to 1x 8 pin adapter and 2x SATA to 1x 6 pin to power the card. Now I read MVC doesn't really approve of those 2x6 pin -> 8 pin adapters. Are there any other solutions except for an external power supply?
