Lol! Thats the shaver I use.
Anyway, I'd go with either the x300SE(does that come in PCI/APG?), or the 6200. They're pretty much on par. The X300 does a lot better in Oblivion, and the 6200 does a lot better in quake 4. Not quite sure about flight sims, but my friend has the X300 , and he plays a lot of flight simulator games, including the one you mentioned, and he seems to be quite content with it. UT 2004 will run great
