Hey,
I've successfully installed Snow Leopard 10.6.3 on my PC. I used EFI Strings to install my GTX295. I get 50-100FPS in Team Fortress 2 with AA and full graphics, but when I watch a video or install something, the windows animations become very laggy, not smooth at all. So, multitasking sucks on my hackintosh.
Why ? Quartz is enabled.
