I tried a HIS HD4350 DDR3 in my Dell Optiplex GX270 and just got a black screen. HIS tech support says that 4000 series cards (and usually 3000 series) don't work with old motherboards because they cannot tell where to send the video. Yet, I search on here and see a bunch of threads recommending higher end cards for this system. Newegg has a review of the 4670 working on this system. I don't have another machine to try the card in...do you think it is just a bad card?
So I really want to get another card if this one doesn't work, but I need to know what is the best one that the computer will recognize and actually work with. All I want is to stream internet video (HD hopefully).
This is such a common old computer. What has worked for you guys?
