I've had my 64Megger for several months and have loved every minute of it. It was a giant leap over my GF2 GTS @ 250/370, made all games smooth at 1024x768*32bpp. I'm now playing around with the BIOS from a Radeon 9100 and it seems to work well. I got it for $90 at Newegg, the Built-by-ATI one and it has 3.3ns memory so it overclocked well to 300/305 before volt modding/cooling. $40 is, like Killrose said, a steal. Make sure to use the Catalyst 2.5, 3.0a, or Omega drivers, and check out the wealth of information at
Rage3D (and that sweet tweaking tool, new version 2.7 came out hours ago) if you get it.
