Honestly, we have no budget for this, so I'm thinking $20-25 max (saw identical cards as the one that died on ebay for $20 w/free ship, and it has to be ebay or another site that takes paypal as our CC is to the max).
As for specs from the vista welcome center page...the pc is a Dell inspiron 530
Widows Vista Home Basic
Pentium Dual CPU E2180 @ 2ghz
Intel G33/G31 express chipset family
Have a flat panel monitor but no HDMI port
I don't game on the PC, it's mainly used for downloading videos, burning videos to dvd, streaming video to my PS3/360/Roku, and internet. I really don't even use it for watching video either, just previewing stuff before I burn it off.
