Even if you could crossfire a 7850 with a 7790, it would just downclock itself to match the 7790. Don't waste the money and just grab another 7790.

Depends. 1) Does it have two PCIe connectors?
2) What brand and model is it?

Then you're going to need an upgrade, yes.

You need a power supply with two PCIe connectors, and one that's relaible; cooler master isn't.

I'd recommend a 500 or 550w by corsair, seasonic, or xfx.
