I just bought this card, plugged it in, installed everything and it runs dam good. But I noticed something odd, when I go to dxdiag and under display it shows that I have 4096 Mb video memory. When I run 64-bit dxdiag it shows only 751 Mb. GPU-Z shows 2048 Mb as it should. Anyone knows what is up with that? I thought the old HD6770 drivers were the issue but i sweeped all AMD drivers before uninstalling new ones.
