Busted GFX cards, what replacement to buy?

[Shadowfox]

I'm getting an error since a couple of days in pretty much any game I play, something with directx and my gpu hanging/getting removed?
I've tried running on 1 card (to check if either of the cards were kaput or even the power supply), error still happened. When I tried deinstalling my GPU drivers my windows went kaput so I reinstalled everything and still the error occurs on this fresh installation.

So I'm down to replacing the GPU's (2x HD7850) and possibly even the motherboard (maybe one of the PCI-e sockets are broken?)
The question is ... which one to buy? Those R9's range from €150 to €450 but I don't really know what the difference is.

Anyone has any experience with these R9's? And if I'm changing my motherboard, which one would you take? (intel i5 2500k)

R9 280X is a excellent card. Thats equivalent to the 7970 Ghz.

But a 290 or 290X is amazing too, whichever you can afford really.
Caveman has 2 290X I believe.

And I am fairly sure Hangover has a 290.

I myself have a 7970 and the performance is great. I run almost every game maxed out, consider the 280X is faster than my card, it should do you fine too.

Yea , the R9 series or 290x can run pretty much every game on high-ultra.
Im not dat much of a hardware guy , u should get advice from Caveman he is an AMD user , or JimmyD :)

Buy the R9 290 with tripple fans. You only need one card.

This is what i use. It´s a very good card.
