The 650i SLI chipset is marketed as a less expensive SLI solution compared to Nvidia’s flagship 680i SLI, so comparing the two comes naturally. What better board to use as the 680i baseline than Nvidia’s own design ? Representing the reference design is the ECS PN2-SLI2+ with BIOS P25.
The 650i SLI doesn’t officially support DDR2-1066, yet the majority of performance motherboards are completely stable using it. Corsair’s XMS2-8888 was chosen for its low CAS 4 latencies at this astronomical speed.
The only board that didn’t completely support DDR2-1066 was MSI’s P6N-SLI (non-Platinum), which consistently became unstable after several minutes of using this setting. The P6N-SLI was perfectly stable at a slower 800 MHz data rate, but keeping all systems at the same setting was most important for an accurate performance comparison. Since retesting every board at DDR2-800 was not an option, the P6N-SLI was dropped from performance charts.
The best performance comparison is one with relatively few "bottlenecks," so the Foxconn 8800GTX was chosen for its graphics power
Finally, a faster hard drive might not do much for the majority of benchmarks, but who builds a fast system with a slow drive ? Western Digital’s WD1500 Raptor was thus chosen.
