I am making a new gaming PC.I have a radeon hd 6670 2gb in my current PC and I am getting a new video card for my new PC. It is not crossfire compatible with the 6670, so I was wondering if I could have the 6670 in my mother board just for my second monitor without crossfire because I don't want to throw it out from my current PC. Thanks.

You can do that, but it's a waste of money to get a second GPU just to use a second screen.

That generally works, but it depends somewhat on other factors such as your motherboard's PCIe support and whether your power supply is up to the task of two video cards. Additionally, there is no performance advantage in this. Crossfire or SLI is required for multiple video cards to cooperate. While you can typically have two in your machine, you're either using one or you're using the other.

The overriding issue is, why? Its very easy to find a faster video card than that HD 6670 today for fairly little money. And for what its worth, the HD 6670 probably has support for two monitors on its own.

No, I need a new GPU because the 6670 is not very powerful and I need to get a new one. I am building a a new pc so I dont want to waste my current GPU which is the 6670.

Sorry, misread your opening post.
Use the new card for both of the monitors (a second monitor for browsing/videos doesn't really need a lot from the GPU to run). Using the HD 6670 for the second will only create more heat, noise, and power draw.

It would be nice if the 6670 can be used as an AMD TressFX GPU akin to NVidia's PhysX, but no such tech feature exists. Do what I did and store the old GPU in a safe place just in case your new GPU ever fails.
