Video Upgrade

I upgraded my Gigabyte 3D1 video card (dual 6600GT SLI on one video card) to a ATI Radeon X1900GT. 3DMark06 scores went up a bit:



Gigabyte 3D1:

3DMarks: 2705

SM 2.0 1076

HDR/SM3.0 1071

CPU 1464



Radeon X1900GT

3DMarks: 4376

SM 2.0 1693

HDR/SM3.0 1896

CPU 1515



Overall it looks like about 60%- pretty decent. However, it looks like my card is not 'unlockable' to upgrade to 16 pipelines (currently 12):
