NVIDIA nForce 680i SLI Preview
For our next round of synthetic benchmarks, we ran the CPU and memory performance modules built into Futuremark's PCMark05 suite.

"The CPU test suite is a collection of tests that are run to isolate the performance of the CPU. The CPU Test Suite also includes multithreading: two of the test scenarios are run multithreaded; the other including two simultaneous tests and the other running four tests simultaneously. The remaining six tests are run single threaded. Operations include, File Compression/Decompression, Encryption/Decryption, Image Decompression, and Audio Compression" - Courtesy FutureMark Corp.
All of our Core 2 Extreme X6800 test systems performed similarly in the PCMark05's CPU performance module. The EVGA nForce 680i SLI motherboard finished right behind the 975X Express, followed by the nForce 590 SLI Intel Edition.

"The Memory test suite is a collection of tests that isolate the performance of the memory subsystem. The memory subsystem consists of various devices on the PC. This includes the main memory, the CPU internal cache (known as the L1 cache) and the external cache (known as the L2 cache). As it is difficult to find applications that only stress the memory, we explicitly developed a set of tests geared for this purpose. The tests are written in C++ and assembly. They include: Reading data blocks from memory, Writing data blocks to memory performing copy operations on data blocks, random access to data items and latency testing." - Courtesy FutureMark Corp.
PCMark05's memory performance module had all of the Core 2 Extreme X6800 systems finishing within a few points of one another. Technically, the 975X Express finished in first place, followed by the nForce 680i SLI and then the 590 SLI Intel Edition, but the <100 point spread between the three is hardly significant.
