I think you should add the <b>X300</b> and <b>X600</b>, along with the <b>R9250</b>, and of course add the <b>PCX</b> series. Just this past Thursday I was using an X300 in an HP box at FutureShop on an new 23" HP 1920x1200 LCD, nice capable card, funny thing was I couldn't see the driver version because in the place where the driver version is listed it simply said HewlettPakard, so it's obviously a version of the (likely older) Catalysts. Anywhoo those cards are now out there, so adding them would be a good idea. If you need reviews of these cards let me know.
<font color=blue>"GeForce 6800
Pros- DX9.0c support, Pixel Shader 3.0 support, very fast at high resolutions, very good AA and good AF performance, Hardware MPEG Encoding (needs software support)
Cons- None"</font color=blue>
Actually the AA/AF is <b>Terrible</b> oftenbeing beaten by the R9800XT (only in this area). The GF6800 is a better card 80+% of the time, but turning on AA/AF drops it below the R9800XT in many cases (which has better quality). So if you were to mention anything about AA/AF I'd say the quality appears better than last generation of FXs, but the performance hit is considerable, and can drop the performance below some last generation card.
I'd also mention that the price it's found at right now, you get a tremendous boost from moving to the GT for little money.
Also, are you going to add the GF6800LE?
<font color=blue>"Radeon X800 Pro
Pros- DX9 support, very fast at high resolutions, good AA and very good AF performance
Cons- Expensive, not as fast as GeForce 6800GT"</font color=blue>
I wouldn't go THAT far. If you've got the FX5700U as a recommended card and not a card to avoid with all it's drawbacks and it's competition, then the X800PRo isn't a card to avoid either, just not as great in all other apps. BTW it will beat the GT in a <b>few</b> apps (~75/25 split). Also you don't mention that many can be moded to XT levels (as SpeedUK did her in the forum).
