Hey Guys, I recently bought a GTX 660Ti Graphics card for in my 8-core mac pro 2010. It works fantastic!! however i was wondering if there is a possibility to run two of those in one Mac Pro without using a external PSU. I know you only have two 6pin connecters in the Mac Pro, but is there a way you can split each connector so that you will have 4 6pin connectors instead of two? that way it would be possible to have two GTX 660Ti's in a single Mac Pro, right? and what about the PSU, will it be enough? i've read somewhere that the Mac Pro's PSU is about 1000 - 1300W. But i'm not sure though. Please let me know because i would lóve to have 2 of these amazing graphics cards!
