Seriously!!! The 5900xt can't play HL2 in DX9? I thought it was a DX9 card or is it just for this game?
Well technically I am not correct. 5900xt can play HL2 in DX9 mode, the problem is that it incurs a tremendous performance hit. For this reason, the developers of HL2 have specifically "forced" DX8.1 mode onto 5900 series of cards.
The visual difference isn't to die for, but it's certainly there for dx8.1 vs dx9.
Here are some comparisons:

DX8.1 vs DX9.0 specifically
Now the performance hit that 5900xt takes in DX9.0 makes it unplayable with DX9.0:

For this reason I would recommend a graphics upgrade above all.
If you want, you can compromise by getting Socket 754 for $70 + A64 2800+ for $130 and Geforce 6600GT AGP.
If I was you, i'd probably overclock 2600+ to 3200+ speeds and get 6800GT.
Also whatever components you are going to upgrade, see if you can sell them to someone to help finance a portion of the upgrade.
