Yeah the reviews are excellent, fucking huge card though, 3 slots! It needs 1 x 8 pin and 1 x 6 pin PCI-E cables though, so make sure one of your cables currently connected looks like this:
so the extra two pins might be unconnected and hanging off the side. If not, can the cables be taken out of your PSU? Because then you can just buy an 8 pin PCI-E. If you cant take the cables out, then youll need a new PSU, in which case I would just go for the 560ti.
