Hi all, Just bought the EVGA GeForce GTX 770 4GB Dual w/ ACX Cooler for my early 2008 mac pro. I've done a lot of research on this forum and I'm glad to know that this card will work with proper adapters. I also plan using precision X to regulate it's power supply. My one question though is that I'd like to keep my ATI Radeon HD 2600 XT 256 MB just for boot screen purposes. Can I have both graphics cards in my mac pro hooked up at the same time? Thank you!
