NVIDIA's SLI: Part 1 - Motherboards

Test Setup:

AMD Athlon 64 FX-55 (operating at 2600MHz - 13x200); 2 x 512MB OCZ Enhanced Bandwidth PC3500 (operating in dual channel with 2.5-2-2-5 timings); Western Digital 200GB Caviar SATA 150 Hard disk drive; OCZ PowerStream 520W Power Supply; Windows XP Professional Service Pack 2; DirectX 9.0c; NVIDIA NForce4 Standalone chipset drivers, version 6.53; NVIDIA Forceware 71.84 Display Drivers.

Motherboards:

• ASUS A8N-SLI Deluxe;
  
• DFI LANPARTY nF4 SLI-DR;
  
• Gigabyte GA-K8NXP-SLI;
  
• MSI K8N Diamond.

Summary:

In general, there is nothing to split between the four motherboards in general scenarios, and all seem to have been implemented very well. There are slight differences in unbuffered memory bandwidth, but the other tests show that the differences are not that great - you are not likely to notice the slight differences in day to day use of any of these four motherboards.
