Hi-Res Gaming Multi-GPU Tests

For our next set of tests, we moved on to some high-resolution graphics benchmarking with 3DMark Vantage, ET:QW, and Left 4 Dead. For these tests, we've tested a Core i7 870 powered system outfitted with single, or dual GeForce GTX 275 (SLI) or Radeon HD 4890 (CrossFire) graphics cards. Due to the fact that these new Core i5 and i7 800 series processors feature integrated PCI Express lanes, and the graphics cards essentially connect directly to the CPU, we wanted to see how graphics performance and multi-GPU scaling were affected in more GPU bound circumstances.

High-Resolution Gaming: 3DMark Vantage
Taxing the Whole Rig

Both the GeForce GTX 275s and Radeon HD 4890s showed solid performance on the Core i7 870 / P55 Express platform, and scaled properly when switching from single to dual-card configurations. The GeForces held a sizable lead here, thanks in no small part to their support for PhysX, which is used in this benchmark.
