VRAM is the frame buffer. The faster a graphics card is, the more data it needs to keep close at hand to crunch. Otherwise, the graphics card is starved for data. Just like the G4 - yeah, it can crunch data really fast, but the bus speed is so slow that it can't actually get the data fast enough to take full advantage of the processor.
Yes, the Radeon 9200 is a low end card. Well, NOW it is. It's basically a refined version of the Radeon 8500, ATI's highest end card a few years ago. All Radeon 8500s have at least 64 MB of VRAM, and I would guess that a majority have 128 MB. I'm not saying VRAM = performance, but too little VRAM = not living up to potential. Because the card is so starved for data with only 32 MB of buffer, it really won't be any faster than the Radeon 7500 in the previous eMacs. The really frustrating part is that the eMac could have graphics MUCH faster than the previous one if they just added the $5 or $10 needed to up the VRAM to 64 MB. I mean, face it... 64 MB is standard for a low-end machine now.
