If you can put a machine together for $250 that can run HL2 decently (as in you won't get 0wned for any other reason than net lag or poor playing skills, not your rig slackin'), I'll eat my Xbox.
The first post is pretty interesting. Recommended, a 2.4GHz CPU. That's a wee bit more than your $250 P4 1.5GHz.
Hell, I could drop a faster Athlon XP in the rig I got now and buy a new video card and I'd easily break the $250 barrier. There's no other way to look at it, if you don't already have the computing muscle, HL2 is a damn expensive game.
