New PCIe SLI Benchmark Help

Hello,
I'm currently working on a project where I would need to stream hi-resolution (4069x4069 & 4096x2048) video onto the graphics card and I'm currently trying to define the specs of both the video and the graphics card.

So far I've tested this on an SLI'ed system that uses a PCIe16 and a PCIe4 to very bad results. It seems when SLI'ed it just defaults to the slowest bus speed. In this case, PCIe4x. Does anyone have a new 2xPCIe16x or even better 3xPCIe16x system on Windows XP that would be willing to run a quick bench mark test for me?

The benchmark is NOT a video. It is a single executable that is 87k compressed.

So far I've only gotten this run at 20fps on a Quadro 4500. :( 

Edit: Forgot to mention. Press space to go into 2 PBO (Pixel Buffer Objects) it should run a bit faster on most machines. Check the command prompt for the FPS.

Thanks a ton in advance.

Is the filesize 141kb and available on Limewire as 'Fly hoochy shows her poochy.wmv'

I have dual 8800GTX Slied on dual 16X PCIe. Your video file is probably ENORMOUS and I would gather your Hard drive throughput even on a Raptor X (which I also have) would be hitting a wall trying to push that huge file along, 60fps??? Maybe a 4 Raptor Raid array on dual link PCIE uber high res monitors would you be able to process this monstrosity of a file natively.

Its actually not a video at all. It's a single exec that just swaps automatically generated gradient texture and its extremely small.

Also hard drive speed is not really important in this test. Its doing everything dynamically in memory.

Who needs raptors. Any raid0 arrays are better for larger amounts of data.

Raid 0 arrays are pretty good... but slower 5200 rpm raid 0 will still be slower than the 15000 rpm drives out there. For the final design of this system it will probably need a raid 0+0 with 4 15,000 rpm drives.
