Currently I have the following setup.

R9-270x

I am looking for a budget graphics upgrade, and am wondering about a crossfire setup by buying another 270x. will it work? The motherboard has a 2.0 and 3.0 16x PCI-E slots and I am not sure if this will work. If it does, will one or either card be bottlenecked?

The performance boost will be good when it works. That's the thing. It's not guaranteed to work properly with every game. In best case scenarios you get a 95% boost in performance. In the worst case scenario you get the same framerate with increased stuttering.

The amd crossfire isn't recommended because the power usage doubles and consumes a lot. I recommend you getting instead of that r9 replace you're current one with an r9 380. It had full directx12 compatibility and higher performance. You'll see a massive difference.

You can run crossfire 270x on that board fine.
Bear in kind crossfire doesn't work properly in ALL titles but in the ones it does its a very powerful setup.

I'd always personally go a hettercsingle GPU but if you Dan grab a 270x relatively cheap then yes - its worth doing as long as your PSU is upto par.

Yeah I understand why a better single gpu is better, but I'm looking for best value for money. I can pro ably get another 270x cheap. Just want to make sure that it will be a good boost in performance per dollar spent
