Upgrade Graphics Card

[atmywitsend]

At the moment I have a Evga Nvidia Ge force GTX 570 Classified installed on a Asrock Z77 Extreme 6 MoBo, I would like to take advantage of the PCIe 3.0 slots and was wondering what would be a good up grade for a new graphics card, so I can see a difference in performance, I have £300 to spend, anybody got any recommendations ?

What cpu and psu do you have?

What resolution?


If the above tally up, then these are worth considering (slightly over budget but worth it) :
