Best AGP card to give old system bit more life?

Have an older system I'd like to give a bit more life to.

I plan to get a new system in 6-12 mos so I don't want to spend too much. Haven't played any games since Half Life 2.

I just downloaded HL 2: Episode 2 and I since replaced the video card with an older NVIDEA NVS and the game requires something the card doesn't have.

The unit is a 6yr old P4 3.00Ghz. So, I'm not expecting to be able to play new games with whatever I get. Will probably pick up a few older games I never played.

Looking at newegg's AGP cards...What is better:

SAPPHIRE 100258L Radeon HD 3650 512MB 128-bit GDDR2 AGP 4X/8X HDCP $63

or

JATON 3DFORCE6200Xe GeForce 6200 512MB 64-bit GDDR2 AGP 4X/8X Low Profile Ready $65

or

EVGA 512-A8-N403-LR GeForce 6200 LE 512MB DDR2 AGP Graphics Card $39.99 (seems like a great deal from amazon)


Thanks in advance.
