Herein lies the main problem. If it isn't a reference PCB, things most likely won't line up properly with the waterblock. Some companies make blocks to fit a specific aftermarket PCB (EK DirectCUII springs to mind) which is nice.
Edit: as for OC capability, I had an ASUS 7970 DC2T flashed to Matrix bios that could "only" do 1175, this thing had fancy digi 12 phase power.
This MSI 7970 TFIII I have now is a reference PCB but with one extra power phase (ala R9 280X) in the place where AMD left one off originally and can do 1200.
