Can an upgraded Blackbook handle TF2 w/ VMWare + XP?

So I just bought my Blackbook about 2 weeks ago and I am absolutely loving it, but I miss not being able to play some games that are only on Windows (and some apps). My MB is 2.4 GHz Intel Core 2 Duo and has 4GB 667 MHz DDR2 SDRAM, and I am wondering if this is optimal enough to run TF2 (Team Fortress 2) under VMWare. How it looks has never been a big deal for me so I wouldn't mind setting TF2 on lowest setting (I considered portability to be the ultimate factor in picking up an MB over an MBP), but I want to make sure that my laptop can handle it before I go out of my way to buy an OEM copy of XP pro and VMWare Fusion.

Thanks in advance!
