Testing (continued):
FutureMark 3DMark Vantage:
3DMark Vantage was run a second time on each configuration, this time in "High" mode which uses a 1680x1050 resolution. This time the HD4890's GPU score gets beat by the GeForce GTX260 at stock speed, while the modest overclock gives it quite a surge.
World in Conflict:
A DirectX 10 benchmark integrated with World in Conflict was executed with a resolution of 1680x1050, and with settings on high. The benchmark provides results in terms of a minimum, maximum, and average frame rate value, and higher is better for all three. There shouldn't be any problem running this game with the settings turned up...
