Upgrade help

[RHendy]

Hello.

I'm looking to upgrade my system that I bought back in 2010. I have about £200 - £300 as a budget.

The current specs are:
Intel Core i5 760 2.80GHz @ 3.80GHz
Asus p7p55d-e
Corsair Memory XMS3 4GB DDR3 1600 MHz
GeForce GTX 480 1536MB GDDR5 PCI-Express Graphics Card
500GB HardDrive
650W Corsair PSU

I've started noticing frame rate drops in newer titles like Bioshock: infinite and Crysis 3 and with battlefield 4 around the corner I feel like it's time for an upgrade! Any help would be much appreciated

Wow very quick replies, thank you

The CPU cooler I have is a "Akasa AK-CCX-4002HPV2 Venom CPU Cooler"

So a 7950 would be best for my price range then?
I think I would probably prefer brand new items if its a matter of a few extra pound.
