First off, let me just make sure that it is possible to crossfire the R9 270X and the HD 7870, right?
Second, is cross-brand crossfire possible? The two brands would be Gigabyte and Diamond.
Only reason I was wondering was that the Gigabyte 270X is a better deal than the Diamond 270X, at least on newegg.
Not that I really need an upgrade anytime soon, I was just exploring my options for the future.
