I have an old, cheap Cyberpower desktop that uses a K8T800 Msi Via motherboard. It came with an AGP Nvidia MX 4000 graphics card, but recently the card failed (the screen would flicker, random crashes, etc., updating drivers didn't fix anything, and it worked for a while with the graphics card disabled, but now I can't get any signal at all when I boot my computer).
At any rate, I'd like to keep the PC around as a second computer but I need to find a reasonable graphics card replacement that will work with the motherboard.
What's a good value/decent gaming performance option? $25-$75 range hopefully.
