Hi everyone, I have powercolor 270x PCS+ gpu and an ECS H87 mobo (http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?DetailID=1460&CategoryID=1&MenuID=172&LanID=0). I have entered a certain competition and luckily won another Powercolor 270x PCS+ gpu. Im thinking of multi gpu setup, will the performance decrease that big since i only got a 2nd pcie slot with 4x and 2.0 revision?
Please help, I have a mobo that has a pcie 3.0 x16 and pcie 2.0 x4. I want to crossfire 270x, will the performance suffer?

Yes. A 4x PCI-E 2.0 slot is not enough to get worthwhile performance returns from crossfiring R9 270Xs. I'd recommend an 8x PCI-E 2.0 or an 8x PCI-E 3.0 for the second card, to make it useful.
Even then, I typically don't recommend crossfire or SLI. Just way too many problems to be a good choice for most people.
