Well the vid card I ordered from TiE, it got here a couple of weeks ago, but due to some shipping problems, I wasn't able to fix it until today.
I went from barely being able to run Halo PC ( 640 x 480, everything ether off or low, and it still lagged a good 20 percent of the time ), to running it at full everything, at 1280 x 800, with almost no lag. Hopefully once I get more RAM there will be no lag.
I have yet to test it with any other game. But I'll be sure to post the leap it makes in HL2.
