Well, the question isn't so much if I can run it; I know my hardware is far beyond what is needed...but I can't figure out if my video card is supported.

I just built this machine on Saturday, and it was my first build. It went smooth, other than me being an idiot and forgetting thermal grease XO.

I plan on dual booting, but I have already install Windows XP Professional Edition SP 2. Can I install OSx86 on my second HDD without messing with Windows?

Here is the machine:

Motherboard: GIGABYTE GA-EP45-UD3R LGA 775

CPU: Intel Core 2 Quad Q6600 Kentsfield 2.4GHz LGA 775

RAM: CORSAIR 4GB (2 x 2GB) 240-Pin DDR2

Video Card: HIS Hightech H487QT1GP Radeon HD 4870 1GB 256-bit GDDR5
