7790 1gb + 260x 2gb crossfire?

[unsoft]

I have radeon 7790 1gb gigabyte.
I wanna buy 260x 2gb and get them working in crossfire.
Is it do have sense ?
I will get almost x2 performace boost ?
As i found two 7790 give big fps boost :

but with 260x ?
Or better is to wait some time and then buy something stronger ?

The 260x's vram will throttle down to equal that of the 7790, you better off buying a second 7790 to match performance and vram. Also, two gpu's does not mean 2x the performance. You will get an fps boost, but not as much if you were to save up and get a better card. Save up and sell your 7790 and get something better than rather crossfire different cards. Many great cards are in the 300 dollar price range.

I agree with TysonY2, wait and save for a more powerful GPU. More importantly, you'll need a GPU with more VRAM to make use of the high end upcoming games.
