Purchased from Newegg a couple of months ago but found out that it's incompatible with my aged motherboard, and I waited past the RMA date.
PCI Express 2.1 x16
Radeon HD 5450
1 GB 64-bit DDR2
Directx 11 and OpenGL 3.2
1 HDMI, 1 D-SUB, 1 DVI
It was only in my machine for a few hours of testing on and off. I'm pretty sure it will work properly on a modern mobo, but if not let me know, of course.
I originally paid $55 plus shipping for it, anything close would make me happy.
