Hey guys, There are a million threads that cover various cards that are useable in a Mac Pro, to various degrees, but I was reading a performance-per-dollar article on Toms Hardware about some of the more inexpensive cards that are out there these days, and I was having trouble finding information on a lot of them with regards to performance/issues in a Mac Pro, so I thought I'd fish for information from people who have used them. I was looking in the CAD $150-250 range, as I'm finding my Nvidia 8800GT isn't quite keeping up with some newer games. I came across these options and wanted to see what people's votes were for easiest/most reliable from an installation/usage/flashing (if needed) perspective: ATI Radeon 7770 1GB ($110-140 locally) ATI Radeon 7790 1GB ($140-160 locally) Nvidia GTX650 Ti/Ti Boost 2GB ($150-170/$175-200 locally) Nvidia GTX660 2GB ($200-240 locally) Radeon 7870 ($230-270 locally) My usage will PRIMARILY be gaming via Bootcamp, but I want to REPLACE the 8800GT as my primary/only GPU, and would like to have the Option-key boot screen as well as have it fully functioning within 10.7 (although I have a copy of 10.8 that I could install if needed for driver support). I'll be using it with a DVI/VGA capable LCD monitor, as well as with an HDMI connection to my TV (I'm currently using a DVI/HDMI adapter for this). HDMI/MiniDisplay Audio support would be a huge bonus. In a PERFECT world, if I don't need to bother with a new Power cable/adapter from what my 8800GT uses that would be great but not a big issue. Does anyone have any direct experience with any of these cards, in this type of application? Thanks!!
