I'm not a complete newb at this - I put together a Leopard Hackintosh already, and that works just fine. However, when I tried to install 10.6 (SL) about a year ago, I had a graphical error and I couldn't find a solution, so I left it.
Is it possible now to get 10.6 running with an ATI 4850?

My hardware (works with my current 10.5.8 setup):
Motherboard: Gigabyte EP45-UD3R
CPU: Intel Q6600
DVD-Burner is ATA
