Company Of Heroes: Opposing Fronts DX10
In Company Of Heroes: Opposing Fronts, the BFG GTX 280 OCX has enough of a performance boost over the reference-clocked GTX 280 to keep up with the Sapphire HD 4870 X2 at 1,680x1,050. However, as the resolution increases the HD 4870 X2 manages to establish a considerable advantage.
At the 2,560x1,600 resolution the 512MB-equipped Radeon HD 4870 shows a high degree of variance from run to run, so take the number with a pinch of salt.
Put simply, at 2,560x1,600, in CoH: OF there is no way that an NVIDIA GeForce GTX 280, however much overclocked, can beat a Radeon HD 4870 X2 2GB.
