Pros: Large heatsink, OC'ed ram and GPU out of the box: definitely features any gamer wants from a video card. The more recent drivers have also improved my framerate (using catalyst 7.3 right now). 630 (575) MHz gpu, 770/1540(700/1400) ram (ram is reported incorrectly as 730/1460 on newegg's spec sheet), these are the values out of the box (compared to a normal X1650XT's speeds).
Cons: No temperature sensor. Even with a heatsink this large, temp sensors can warn you of fan failure, dust buildup, etc. OC settings are at the limit, which has lead me to: Artifacts. Using Google Earth I get artifacts 30 seconds after launching it in the default opengl mode (no problems in DX9). WoW also develops artifacts after about 2-4 hours of play (DX9 mode). Haven't seen artifacts in other games like SupCom, NFS Carbon, ST: Legacy, or 3DMark yet (all ran in DX9), but I haven't had time to test it extensively.
Overall Review: To solve my artifact problem, I reduced the speeds to 621 MHz cpu, 756/1512 MHz ram. I tried several different driver versions (both from ATi and modified ones), and each produced the same artifact problem. The large heatsink will block a neighboring expansion slot. If you have a small PCIe 1x card you might be able to get them to fit, but longer boards will block the video card's heatsink fan inlet.
