[SOLVED] Way to see your detailed video card specs?

Hello. I just recently purchased a Radeon HD2900PRO and installed it. It is working wonderfully.

However, I purchased it from ebay, it is new open box, and I can't find anywhere on the box where it says what the memory bus interface is.

I have heard that there is a 256-bit interface and a 512-bit interface for the HD2900Pro and I can't figure out which one I have.

I opened up the Catalyst control center menu and under the Graphics Hardware it lists a bunch of things but none of them are what the memory bus width is.

I have seen pictures of software before, most likely for overclocking that had all of that kind of fancy information on it.

I am just curious as to what this card is using.

Thanks for reading.
