NVIDIA's Double Graphics Whopper: SLI Comes to Market

Test Setup

We tested the SLI configuration with GeForce 6800 Ultra and GT with both the ASUS and MSI motherboard. We only gathered comparison data for single-card operation from the ASUS board. We used an Athlon64 4000+ (corresponds to Athlon FX-53) and 1 GB RAM as a CPU. For the Power Supply, we used an Antex True Control ATX (1.0) PSU with 20-pin main power connector. We did not face any power issues during our tests. We also tested a 760W workstation PSU, just to see if our stability problems had to do with power.

Due to the stability problems described earlier we decided to forego overclocking tests.
