new help on GPU upgrade

[p0634715]

Hi currently using a powercolour 5850.

Recently just bought a dell 2713HM.

Just wanna know what GPU can i upgrade to without bottlenecking.

PC spec:

P2X4 955
TEAM ELITE DDR3(8GB)
Andyson F600M 600W

Hopefully able to game at 1440p at High settings (BF4, COD etc.)

Without getting a new system.

Cheers
