Memory performance
I'd best warn you up front that the following set of benchmarks is not likely to evoke a cathartic, life-changing experience. You're in little danger of forgetting to breathe, either, although you may well doze off for a second and slam your forehead into your keyboard.

Because the Athlon 64 processor has its memory controller built in, performance differences between A64 chipsets are potentially very small, especially when those chipsets are implemented well. Such is the case with all three of the motherboards we've tested here. Any significant performance differences we'll see in these tests will likely come from several sources, including differences in BIOS and motherboard implementations. One of the few notable differences between the nForce3 Pro 150, the K8T800, and the K8T800 Pro is the speed of the HyperTransport link. The nForce3 Pro 150 is kinda pokey on that front with a 16-bit, 600MHz downstream link and an 8-bit, 600MHz upstream. NVIDIA has addressed this limitation with the nForce3 250 series, however.

Since these results are so scintillating, I'll let them speak for themselves, and limit my commentary on the following pages. I'll discuss things as needed, then sum up at the end.
