Hello, recently I got a 4,1 mac pro, that I wanted also to use for games. I installed windows from scratch (needed to create disk from an iso and boot from it). After that I installed 5.0.5621 Bootcamp drivers. Now i wanted to insert the new graphics card (MSI NVidia 960gtx). But before opening the packaging I wanted to ask some questions, since I didn't got any clear answers by reading the forum for several days. 1. Will the 960gtx run in PCIe 2.0? Some threads say no, some threads say you need to flash etc. 2. Can I reuse the power cable from 8800gt for powering the 960gtx?
