Im looking at getting a new GPU and i'm unsure if the one i want/selected is the best choice for my system.
My current specs -
AMD FX-6300
Corsair H55 cooler
Asus M5A78L-M/USB3
Radeon 7750HD (1GB)
8GB Ram
1TB Seagate HDD
120GB Kingston HyperX SSD
Corsair CX750W PSU


I'm pretty much made up on getting a nvidia GTX780.
Or would I be better with one of the non-reference R9 series?

Thanks for any help!

How do i make the jump manageable for my system? Is it as simple as upgrade the CPU at the same time?
