I found out there are not much differences in speed between x16 or 2.0 PCIe.... There are differences in power which slot can give to GPU - max 75W in x16 to 150W in 2,0 PCIe... On some forums say that the card may have problems with this...
I'll probably have to buy new hardware...

I installed fresh version of Vista Ultimate x64 and problem is the same
Maybe my GPU is broken i don't know. I give you a sign after buy new motherboard.
Thanks all.
Ps. I give bad topic name. Should be GTX 280 on PCIe x16 1.0 instead of 2.0...

That's insteed very strange.
It's definately not the 8x PCI-E slot, as i've had multiple people tell me it works fine with a 8x slot.

Ok so I have a replacement card GTX 260 Everything works on my PCIe x16. GTX 280 has proved to be defective. Waiting for the new GTX 280 and this time I get down to testing Octane:)
Thank you all for your help.

Keep in mind that Cubix has connected discrete Quadro FX 5800 cards via external ExpressCard 34 connection to laptops running Octane Render. While it takes longer than being directly connected in a desktop PC (ExpressCard 34/54 = single-channel PCIe bus), it does run far faster than using the notebook's integrated GPUs, even faster than the most current, state-of-the-art mobile GPUs included in products like the new MacBook Pro series.
My point is this: if the OS sees the GTX card and it still crashes, it's not the bus connection speed that's going to be causing the problem. Faulty graphics cards and other issues would be the cause.
