At both resolutions settings were cranked to Ultra with the exception of Post Process (where medium denotes DX10, and high denotes DX11) and multisampling was left at 8x MSAA.
CMR DiRT 2 is a wonderfully optimized game with stellar graphics quality, all cards performed very well, including the out-classed GeForce GT 240. It appears that the game practically maxes out around 70fps since the GTS 250 was so close to the GTX 260 at both resolutions so not much can be said here.
When in DirectX 11 (Post-Processing: High), the individual cards dropped by about 10fps while the mix crossfire remained right around 70. I am beginning to notice a trend of the mix crossfire being significantly better at higher resolutions.
