Yep, I finally got a new video card! My dad bought it at Fry's for 40 dollars. It's a NVIDIA FX 5500 128MB AGP Overclocked by BFG. I am happy with its performance.
Here's an estimate of the FPS results on these games:
CS/HL: 100 FPS (was 72 before until I realized fps_max was set to 72...and probably the reason why my old card ran at a 72 FPS peak) on 800x600
UT2004 Demo: 35-50 FPS on most settings about medium-low on either 640x480 or 800x600 (I can't remember)
DOOM3: 30-40 FPS on low settings on 640x480
HL2 Demo: 30-40 FPS on low settings on 640x480
Halo: 35-50 FPS on low settings on 640x480
3DMark2001SE: 5280 3DMarks
Do you think it's a good deal? What do you think about the video card? Tell me your opinions!
