PC Apex have a new review up on a nice budget-friendly card from Sapphire.

Images from both cards are exactly what you would expect from any modern relatively high-end card. They are exceptional. Both, however, howed some strengths and weaknesses. Without filtering the Nvidia card had more of a tendency for pixel shimmering than the ATI card. Pixel shimmer is the ugly sparkling that happens where a moving dark object meets a lighter one. It is usually very apparent in vegetation such as leaves on a tree blowing in the wind. At the point where they meet the sky the image shimmers unnaturally at the edges. Even with Bilinear or Trilinear filtering some pixel shimmer is apparent with both cards. But if you intend to run at 1280x1024 or 1024x768, you can still manage very good frame rates with the X1950 Pro with a good deal of both anisotropic and anti alias filtering.
