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.

Okay thanks, do i need upgrade my power supply?

DarkSable · May 13, 2013

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

1) only one
2) cooler master - 460 watt

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.

Yep, that's always the downside to tinkering with computers.
