Thoughts on Acer?

I'm looking to get a new laptop, and since its primary purpose is work, it has to run Unreal 3 well. I'm looking at the Acer 7520-5757, since it has XP drivers and a second hard drive slot. That way I can primarily run XP and have Vista as a secondary instead of dual booting off one hard drive, which did not work for me before. That said, anyone got any thoughts on Acer or on the newer AMD processors? Here's a quick look at the machine:
