i5 760 upgrade

[Guest2]

I'm getting the itch again to upgrade (cpu, ram, board)

Current rig;
i5 760@4ghz
Arctic air cooler
Gigabyte P55-UD5 board
Kingston HyperX 8gb
Crucial M4 128GB SSD (plus 3 1TB drives & a velociraptor)
780 Ti
Xonar Essense ST
Fractal case
Corsair TX850 PSU

Should I try and find a cheap i5 2500k bundle (cpu, board, ram) for ~£150 or maybe a bit less or get an ivy bridge / something else?

To be honest I have no idea if an upgrade would be worth it but would like to sell my current parts and move on before they are worthless

edit - could this be moved to general hardware. Sorry, didn't notice I was in the CPU section

Cheers. The memory is Kingston Hyper X Genesis. black stuff
On the module it says KHX1600C9D3X2K2/8GX

I would probably try and get a pre clocked i5 2500/2600 with memory, board and cooler for ~£150 or a bit over, then just sell my current bundle as it is

Do new boards have a PCI slot still? I need one for my Xonar Essense ST
