Half-Life 2
Half-Life 2, whilst being an exceptional game, is somewhat strange to benchmark. Performance is hugely dependent on the subsystem, so much so that it's subsystem-limited on top-end cards, even with AA and AF applied. All three cards produce decent enough framerates at 1600x1200, too, and SAPPHIRE's card continues to impress as we raise the image quality. The GeForce 6600 GT's lack of framebuffer is the reason why there's no result for 1600x1200 4x AA/8x AF.
