Testing notes
All our systems were set up with an Intel Core 2 Extreme QX9650 processor which, whilst not necessarily indicative of many real world systems built with these boards, will help to highlight any visable performance differences.
There are two Intel boards (one DDR2 and one DDR3) and two NVIDIA boards (both DDR3). All four systems utilise 4GB of RAM in the form of 4x1GB modules.
The DFI LANPARTY LT X48-TR2's memory was run at 800MHz with 4,4,4,12 timings due to the difficulty in getting them stable at 1,066MHz with 5,5,5,15 Timings.
On the DDR3 side the DX48DT2 couldn't be run at the desired timings due to the 'Intel knows best' overrides in place. As such we had to run the tests at the SPD default timings which are notably slacker than desired. Until Intel fixes this issue however, the results are indicative of the performance an end user would achieve with our specific components.
For our gaming tests we will be using a GeForce 8800 GTX for single-card numbers on both the Intel and NVIDIA platforms to get a cross-platform comparison, whilst our multi-GPU tests will be using up to three HD 3870s in CrossFire on the Intel platform, and up to three GeForce 9800 GTXs on the NVIDIA platform, in order to get an idea of the platform's scalability.
