What GPUs will fit in the case of my ATC-605-UB11?

Title says pretty much everything. I'm looking to upgrade my GPU and I need to know what size my case can handle. You can find the specs here: http://www.newegg.com/Product/Product.aspx?Item=N82E16883103924
I'll also get a better PSU if I need one!

I guess no one can help me out
