http://www.evga.com/ocscanner is a free tool for EVGA owners to benchmark graphics cards. It looks ugly on wine, probably because of http://bugs.winehq.org/show_bug.cgi?id=24890 ( LWA_COLORKEY support missing ), and it can't detect gpu temperature, etc., but the benchmark part works great under Wine. And since it's an OpenGL app, wine scores quite well. It's the first consumer app I've seen that will tell you if your graphics card is rendering properly; it gives a count of incorrect pixels.
