Can these two cards be run simultaneously?

Hello, recently this Christmas I received a NVIDIA GeForce 1GB GDDR5 GTX 560 Ti graphics card as a gift. Currently, I have an AlienWare computer (also a gift) which has two 1GB GDDR5 Nvidia GeForce GT 545 - SLI Enabled videocards.

My main question is, would it be possible to remove one of the 545s, put the 560 in, and run both in SLI? If this can't be done, is there any way I can run both simultaneously at all?

I am a bit of a computer newbie. In any case that both cards cannot be run at the same time, what would be the better option, the two 545s or the 560? Thanks.

Nope, they need to be the exact same card in order to run is SLI. I would remove the 545 and just install the 560.

So (stupid question), one 560 is better than two 545s? If that's the case, thanks for the info!

Oh jesus, I would assume so. The 545's I don't think are that powerful. Play some games see which you get better FPS in.

In the AlienWare is your Power supply (PSU) a 500w or better and since it is a Dell what is the brand of your PSU? To run the 560 ti it takes a 500w PSU at constant not peak.

The GTX560ti is definitely faster than SLI GT545 (faster than SLI GT545 by about 20%, and you don't need game with SLI support cause it is a single card). Also, I think you will be fine with your PSU since the power requirement of SLI GT545 GDDR5 used in the DELL Alienware is higher than 1 GTX560ti (stupid build really to have 2 low card in SLI that can't outperform a fast card and use more electricity).
