It is time to shift gears to some 3D benching fun and I start with a single BFG GTX 280 OCX which turns out to be only an average clocker on air, so hopefully that means a good clocker under cold. Here are a couple photos including the setup as tested and the volt mods to the card.

The volt mods on the card hardly help with clocks on air and are really a waste of time for most users unless pehaps you are water cooling. Even then, I wouldn't expect much gains from the volt mods. Here are the all air numbers and a complete breakdown of the setup including the updated cooling on the SPP:
- CPU: Intel C2D E8400 (L808A476) @ 500x8 4000MHz
- CPU Cooling: Thermalright Ultra-120
- RAM: Crucial Ballistix 2x1GB PC3-16000 CL9 @ 1:2 1000MHz 8-7-6 / 1000MHz 7-6-5
- NB Cooling: Swiftech MCW30 / MCP655 / MCRES-Micro / PA120.2
- SB Cooling: Thermalright HR-05-SLI
- PWM Cooling: Swiftech MC14 x 4
- GPU: BFG GTX 280 OCX
- PSU: Ultra XPro 750W
- HD: Seagate SATAII 80GB 8MB NCQ
- OS: Windows XP Pro SP3 (fully updated) // Windows Vista SP1 (fully updated)
Vista was obviously only used for Vantage running the Performance preset. Notice the voltages required for the different memory settings run. 01 and AM3 were ran with 1000MHz 7-6-5 and the rest with 1000MHz 8-7-6. Both ran without issue at the same voltage as this kit did in the 790i Ultra. These results are just a baseline for before sub zero cooling on the CPU and GPU, just to get warmed up

The numbers are nice, and shows just how strong this combo of 790i SLI and a GTX 280 is. It is a shame I don't have a second one to pair up with this guy to do some real damage. Either way, next up for this setup will be a Tek9 4.0 Slim and some LN2. I think I will just stick with phase on the CPU as the FSB limitation on this board really won't let me push my E8600 under LN2 anyway. I'll save that for the GTX 260 SLI benching.
