I thought my card was a 1gb, not a 2.8gb. What is up?

In DXDIAG, it tells me that my GPU has 2803mb. I thought the hd6850 was a 1gb card. Why does it tell me that it has that much memory?

lol,your gpu is still 1gb through,your ram would be 4gb as i think,your ram is shared with your gpu memory thats why its showing 2.8gb.well you are

Okay, that is what I thought, but why would my 1280x1024 screen need more RAM?
