Something about my new CrossFire setup seems fishy, and I was wondering if anyone out here knows if it's CPU related.
My D805 is OC'ed up to 3.625GHz. I tested my rig with 3DMark05, and with XFire disabled, I got a score of 9075 (CPU score: 5800). When I enabled XFire, the score went up to 9469 (and for some reason the CPU score went up to 6274). I didn't really expect to see such a small increase in overall score, but I thought that since 3DMark is running at a lower resolution of 1024x768, then my score could possibly be CPU-bound.
Curious, I loaded up CS:Source and ran its Video Stress Test at a high resolution (1920x1200) to see if that fixed my CPU-bound problems. With XFire enabled, my rig only managed 103.17fps. With XFire disabled, the fps actually went up to 107.25.
What's going on here? Shouldn't high-res 3D apps be GPU bound? Is a 3.6GHz D805 really that worthless, or do I have a video card problem? Why would disabling XFire raise the fps? All the drivers are clean, soooo... What do you guys think?
Thanks in advance,
