Want to talk about your hardware setup? Brag about your super-machine's layout? Pretend you know a lot about computers? You can do all that and more in this forum.
Depends on the type your looking for. There are alot of video ram types like fpm, edo, vram and they come in all kinds of socket types and speed. I looked into getting some for my favorite cards and found that your much better off stripping a card you dont want to max out a card you do want. What video card are you trying to upgrade?
I already got the two 512 KB rectangles from another card (that I was looking for). But I found it weird that I couldn't find it in computer stores, no matter what the size/type.
