If I'm not mistaken, the 7500 is the same basic core as the original Radeon. (card is +/- other features, and maybe different speed). I ran a G400 for ages. It has a crystal clear, crisp image, and has given excellent performance. (~100FPS in Q3A @640 in 16bpp) I then purchased a Radeon (64MB ddr w/vivo). It is definitely faster. It will, however, get much faster when the T&L code gets finished and added to the driver, which I'm anxiously awaiting. Currently, I get about 80-200+ FPS in 640x480@16bpp in Q3A--totally adequate. I get good perfomance in 32bit mode, but it just isn't enough. If the level is heavily loaded or there's a lot of particles it dips too low for comfort, so I stick with 16bpp. I imagine the T&L code will alleviate this issue considerably. That's at least what I'm hoping for. The only thing I don't like about my Radeon, is that the image is not nearly as crisp, nor even as stable. My setup is: Video card <-- vga --> kvm <-- vga --> Monitor. But, even with just: Radeon <-- vga --> Monitor it has serious ghosting (8mm @ 1600x1200) artifacts, and if I look closely at the image, it is not steady--little dots are floating around. I live with it because it is so much faster, and I use the video in features--which work great btw. Perhaps I have a bad board, or my cable is too long, but this is what I observe. The G400, even with the kvm in between, does not exhibit this at all. So in short, if you care more about image quality, and/or your eyes are bothered by unsteady display (I'm not, really), I'd recommend sticking with the G400. If you really want a boost in speed, go for the Radeon, and be happy to know that it will actually get faster for free in the near future.
