Is it possible to put 2 video-cards in one pc?

Let me ask, just to make sure I understande. You want to somehow use two video cards for one monitor? Why?

Thanks for looking at my problem

No, it is not possible to have to DIFFERENT GPUs driving the same monitor. They would have to be the same GPU set up in XFire/SLI.

False, it's called physx cards, you can use two different cards and use one as a physx card and the other as a main GPU, however, it's a bit overkill having a 560 as a physx card TBH.

After Nvidia's acquisition of Ageia, PhysX development turned away from PPU extension cards and focused instead on the GPGPU capabilities of modern GPUs. A graphics processing unit or GPU (also occasionally called visual processing unit or VPU) is a dedicated graphics rendering device for a personal computer, workstation or game console. Modern GPUs are very efficient at manipulating and displaying computer graphics, and their highly parallel structure makes them more effective than general-purpose CPUs for a range of complex algorithms, such as accelerating physical simulations using PhysX. A GPU can sit on top of a video card, or it can be integrated directly into the motherboard. More than 90% of new desktop and notebook computers have integrated GPUs.

Any CUDA-ready GeForce graphics card (series 8 and newer, with a minimum of 32 cores and 256MB of video memory) can take advantage of PhysX without the need to install a dedicated PhysX card.
Versions 186 and newer of the ForceWare drivers disable PhysX hardware acceleration if a GPU from a different manufacturer, such as AMD, is present in the system. Representatives at Nvidia stated to customers that the decision was made due to development expenses, and for quality assurance and business reasons. This decision has caused a backlash from the community that led to the creation of a community patch for Windows 7, circumventing the GPU check in Nvidia's updated drivers. To counter this patch, Nvidia implemented a time bomb in driver versions 196 and 197 that slowed down hardware accelerated PhysX and reversed the gravity, but an updated version of the patch removed all unwanted effects.

It is possible to fit two cards or three or four, if you have a suitable motherboard and case, as many people do to provide multiple monitors as far as the system is concerned hardware is hardware, and as long as the required signal is present on the BUS used and there is sufficient power available to drive the devices, there should not be a technical problem

It is also possible to connect multiple sources to one output device, If the output device has the necessary input connections, though unless the device is designed to present multiple simultaneous sources, you would need to select the display source that you actually see. Many people do this daily with their TV, do they not?, using multiple HDM1, SCART, & myriads of other connections, the device does not care what the signal is from, only that the signal is of a usable quality and type.

As to whether it is practical, physically possible, or even useful, this depends on the available hardware, it's capabilities, and the needs of the end user

Beautiful breakdown Nigel, thanks.

I was thinking the same thing PhysX with a 560 ti that is like Napalm + main Gpu 670 good lord you better have a fire exstinguisher ready thats alot of power and can your PSU handle this that is the next question
