Halo 2 vs. Half-Life 2

Well, it's not really like that, but Steve posted that he's tempted to get an Xbox simply to play Halo 2. I'm having similar pains over Half-Life 2. My beautiful wife picked up a copy of Halo 2 for me this morning at Target. On my home PC, I've got a ready to activate copy of Half-Life 2. The problem is, after playing the source beta for Counter-Strike 2, I find that my video card isn't quite up to snuff for the HL2 release. So my conundrum is, do I buy a new video card so that I can play HL2, or do I save myself 250 bucks and just get some of the other great new Xbox games that are coming out this fall? The mind reels...

Update: I'm going to get a new video card and at get the game.(Eventually) I didn't mean to start a Vi vs. Emacs war, my only point was that I don't have to screw with the console games at all. I can just pop a disk in and play it. The PC is a little tougher, as I want to play wide screen and I want it to run well. I love playing Counter-Strike, so there was never really a question that I would get the software. I'm also looking forward to playing with the source code and maybe building a level or two. :)
