GTX260 quicker than GTX690-what have I done wrong?

I have just had a new system built by PC Specialist (UK):-

OLD SYSTEM

Dell Studio XPS Motherboard
i7 CPU 880 @ 3.07 GHz
8GB RAM
GeForce GTX260 GPU
2TB Hard Drive
Windows 7 Home Premium

NEW SYSTEM

Asus Sabertooth X79 Motherboard
i7-3930K CPU @3.20 GHz
32GB RAM
GeForce GTX690 GPU
Intel 480GB 520 series SSD Hard Drive (Boot and programs)
Windows 7 Professional
Caviar Black 2TB Hard Drive (User Files)

Using Sony Vega Pro 11 (not an upgrade from Vegas 10), I opened identical files of c120GB (approx 1hour 20mins HD footage) footage taken at Sydney Mardi Gras this year on both computers. Then set them both rendering to HDV 1080-50i MPEG-2 files.

After the renders reach 4%, the clock starts counting down stating how long to complete the render.

The old computer reached this 'tip-over' point at 3.45mins and indicated 1 hour 27 mins to finish.
The new computer reached this 'tip-over' point at 3.55mins and indicated 1 hour 35 mins to finish.

I tired this several times thinking it might be an anomaly - but the above was the best time the new computer achieved (the worst was 1 hour 57 mins)

For those with knowledge of Vegas Pro, I had ensured that GPU Acceleration was selected in the OPTIONS/PREFERENCES/VIDEO and that the GTX690 was showing in that tab.

Anyone got any ideas? ...... I'm at a loss ...... surely it has to be something really stupid ???

Kind regards

Roy

Everyone says it but ignores it: Nvidia changed their cards to something not compatible with the previous ones, NOT Sony. The obvious issues here is that, NOT Vegas. If the CUDA specs changed in a new card then Nvidia should be scolded for not telling everyone ahead of time.

1. I haven't seen anything about a survey. I have heard of folks getting contacted via email to provide information, but that would not be me. Seeing as I've included my email with every single error report I've submitted, and they've never emailed me back, I don't expect a dramatic turnaround from Sony support.

2. I agree with you about Nvidia needing to tell everyone about the new structure, but Sony is so behind the curve with my favorite NLE that it will take them forever to 'get with it'. Adobe's Mercury engine just doesn't have this problem.

"For now let it render and time the completions. Also please download the Sony Veg test set and post your results in our processor comparison thread."

I understand what you say about letting the render run - but I was only wanting to see why the GPU wasn't working initially - and getting general comparisons. From the posts I'm not in boat foating in the pond with a useless GPU !!

2 weeks since I sent my tickets without a tweet in reply ...... I just perchased CS6 Design Studio ..... and take on board what you say about Premiere.... unfortanately I've spent all available funds on the GTX690 :-(
