What can I do with two different graphics cards on one machine?

ProfoundGlee · Sep 24, 2013

So I just bought an Asus 3gb 660ti but I still have my MSI 1gb 650ti boost. I was wondering what I can do with the old card in this computer?

I have the power and space to put it in, fyi.

There's only two things you can do:

1) Add more monitors (non-gaming) than a single card supports, or

2) Assign the 650Ti as a PHYSX card.

If you use a second card as a dedicated PHYSX card (assign in NVidia Control Panel) it needs to be at least 70% as powerful as your main card or else you bottleneck the main card because it is WAITING for the dedicated card to finish.

How well it works varies between games, and some games have different levels of PHYSX you can choose (Low, Medium, High).

The way to figure out how well the addon card works is an a PER GAME basis as I said, like THIS:

1. Run game with VSYNC OFF and FRAPS to monitor the frame rate.
2. Do NOT assign the 2nd card to PHYSX.
3. Write down the average frame rate you see (preferably a repeatable area).
4. Now assign the 2nd card to PHYSX and retest.

If you get higher frame rates with the addon card then keep it.

There's a 3rd thing you can do, sell the 650ti boost & get another 660ti that matches
your current one for SLI, assuming yoour PSU and mobo can support the 2 cards.

If it came to selling, then I'd tell him to sell BOTH cards and buy the MSI GTX760 for $260.

Everything I saw showed the 760 only marginally better than the 660 ti. And it averages 50 dollars more.
