I currently own a GTX 550 ti, and use it to power 2 monitors. I only game on one of them. I recently was given a third monitor. (I now have 3 17 inch monitors running at 1280 x 1024 each.) However, the 550 ti only supports 2 monitors. I do not want to buy another 550 ti, as it is not necessary (I will only be doing word processing and web browsing on the two side monitors, so do not need the power of another 550 ti.)

My question is, can I buy a cheap GPU (e.g. GT 610 2gb) and run 2 monitors from that card, and then run the center screen off of the 550 ti. I will only be gaming on the center screen, so do not want surround. Will having the cheap GPU bring down the performance of the 550 ti? Is it possible to run the two card at the same time with no driver conflicts? In the future, I will be upgrading the center monitor to a 24". Will this still work, do the monitors all have to be the same?

Completely off topic, can I add an AMD 6670 to the 550 ti, or are they completely incompatible?

Any help is appreciated :)

So long as your motherboard supports two GPUs, you should be fine.

Nvidia requires, at least for the 5xx generation, 2 video cards in SLI to run Surround (3 monitors, 1 desktop). However, it possible to run two different cards and to have those monitors hooked up to the different cards, like you are wanting.

It should not interfere with the 550ti.

The monitors do not have to be the same assuming you only want extended desktop. Technically they don't have to be the same for Surround, but it ends up with poor resolution.

You can add a 6670 if you would like. It isn't as recommended but it is certainly possible.

What do you mean by, its possible, but not recommended, do I have to download 2 drivers, or another program to get them to work together?

Thanks for all the help so far :D

You would need both the AMD driver for the 6670 and the Nvidia driver for the 550 ti.

It is possible though, I know of many people who have done it and it works just fine.
