Thanks for the DIY articles and forum. I currently run a DIY5 system with a Matrox rt.x2. Generally, it's an OK system but I probably need to get a different video card as the rt.x2 seems very finicky about which cards work best. I purchased an ATI Radeon x1950xtx 512MB card and I don't get as much realtime performance as I expected - especially when working on HD projects. I have seen several reports that the x1950xtx is NOT a good match for the rt.x2. (By the way - I did check with Matrox before purchasing and they "recommended" the x1950xtx---obviously without testing performance.)
I would be interested in performance of rt.x2 with DIY7.
Also, I would appreciate recommendations for a new video card. I see that you are advising people to choose the nvidia gtx-260 or 285. Is there a reason that you aren't recommending the gtx 295?
If anyone has advice or ideas on this approach, it would be appreciated.
