Will the XFX 5850 Black Edition (specs below) be powerful enough to play the latest racing games (Grid, Dirt2, NFS Shift...) at full res. on a 27" monitor (2048 X 1152). What kind of performance (fps) should I expect?
Black Edition has core clock of 765 MHz vs. the normal 725 MHz.
Black Edition has memory clock of 1125Mhz(4.5Gbps) vs. the normal 1000Mhz(4.0Gbps)
Yes it will play all those games perfectly, The most demading game there is Dirt 2 and I get a steady 60FPS in DX11 mode with all details at highest settings no AA at 1920 x 1080.
