Ok, so I'm still trying to gather information before I decide which video card to get. Cost is a large part of the equation. I can't really justify throwing $500 dollars at a video card right now. I would love to, but can't. But, I also want to make sure I don't miss getting better performance if I spend just a bit more. 1. MacVidCards has cards that will run full PCIE 2.0 with boot screen. Do stock cards run at 2.0 or 1.0 when in windows (bootcamp)? Is the limitation strictly on the mac side, or both? 2. Looking at maybe getting a Nvidia GTX 560 TI. Do I need the second cable to install like you do for the 570? Couldn't find any info on this. Thanks in advance.
