What do you mean support mame games? Also, you might be able to get a better card for about the same on ebay. For example, an Nvidia 6800 or Radeon X700 or 800 will have somewhat lower clocks, but the bandwidth for them is four times as much (a much more important factor). If you're just looking for good S-video output, then you have some googling to do. Of course, I'd suggest reading the wiki over again a couple times, and then searching the forums for examples of the things discussed in it. There are a few options, and different hardware approaches to address them. And, look at that recent thread on display results, linked in the Video overview.
