If you are getting this card in advance of a new system, I'd say go for it, but...
If you have a little extra cash, you might have better luck spreading the money between a motherboard, CPU, and a lesser graphics card like a 550Ti or 560Ti. You will get better performance from a system wide upgrade at this point then dropping a huge card into an old system.
You also have to be careful for PCI Express 2.0 vs 2.1 changes. There may be some bottlenecks there.
