The GTX 295 will use an internal SLI connection and requires only one PCIe 16x slot to operate.
As such, you do not even require a SLI compatible motherboard to get top performance out of the GPU.
The nForce 200 SLI bridge is used to split PCIe lanes into multiple slots and is only really needed if you wish to run 4 way SLI, AKA 3 way SLI with Physix, on a x58 motherboard.
As the x58 chipset alone only supports 32 PCIe lanes running in 16x 16x for two cards OR 16x 8x 8x for three cards, the nForce 200 SLI bridge will allow you to split the dedicated 16 lane PCIe slot into a two slot 8x 8x combo and allow for the fourth GPU to be installed.

My Intentions is to buy gtx 295 now, and when direct11 graphics card comes next year buy one of them, and then use gtx 295 as sli2 (dedicated phsyx)
Will this be possible?
Does GTX 295 count as 2 graphic card or just 1, when we think about PCI slots? I mean do GTX 295 fill out 2x 16 PCI, so that when i buy another card next year it will only get 8x pci?
To the first question, no, I am not sure if/how that would work for you.
I guess it would really depend on nVidia and how they wright their drivers when a DX11 card comes out.
As the Vista kernel (same kernel as Win 7 will use) can only support one driver for the display devices, both cards will have to be supported by the same driver package for you to have any chance of doing this.
For the second question, the GTX 295 is a single card in all senses.
It will take up one PCIe slot, can run on a motherboard that does not support SLI and should be seen as a single device in your control panel.
There are a few motherboards out with the nForce 200 SLI bridge included.
Just look for an x58 motherboard that has 4 or more PCIe 2.0 16x slots and you will locate them.
TBH, there is nothing special about them as compared to the non nForce boards except for the price.
As I said earlier, the nForce 200 SLI bridge will not give you better SLI performance.
All it will do is let you run more than three GPU's on the board.
You will be better suited getting a motherboard with out the nForce 200 SLI birdge and saving some cash.
i wouldn't be in a hurry to get a board with the nF200 on it if your going x58 anyways. talking small gains for potential problems on a platform Nvidia has little experience with. be grateful for SLI without it lol
