Dxdiag 7890 gpu

[bocybocy]

I've got an issue, I'm receiving low performance on my ATI radeon 7890, manufactured by AMD. Getting lower performance than friends with lesser systems and upon checking my DxDiag I saw something perplexing.

Display Memory: 737 MB
Dedicated Memory: 2027 MB
Shared Memory: 2806 MB
Current Mode: 1920 x 1080 (32 bit) (120Hz)

Does anybody have any idea what my display memory would be getting reported at 737MB on a 2GB card? Could that possibly be my issue and is there any way to change it? Any help would be greatly appreciated.

7890...? I'm assuming this is the 7870 Tahiti LE.

This is probably a problem with Microsoft unable to recognize this new card.
I suggest using GPU-Z instead.

I can give a +1 to the above poster.

My 5870 shows 732 while my 650 ti shows 4045. Both are just 1gigabyte cards.
