Doubtful Zen will even compete with the i5 if history repeats itself, could also be 12+ months until it comes out.

4790k destroys every AMD cpu, a great upgrade in your price range.

However;

If you don't mind spending £300-320 as you'd need a customer cooler. Quite abit better than the 4790k and due to you having to buy a custom cooler (which is where the £300+ pricetag comes from) you'd be able to give it a decent OC. An OC'd 6600k could potentially feel generations ahead of the Zen when it comes out, of this I have no doubt.

Cheers for the reply man quick secondary question could I oc the 4690k with a 500w corsair cx psu h100 cooler and cooler master haf x case seems doubtful but a question none the less pretty sure the 480 and i5 have lower power requirements than my current build

A 4690K and 270X are fine on a 500 W PSU.

Yeah, you have enough headroom for an OC, just don't bump voltages too much imo. Plus, there's a certain limit after which you hit diminishing returns.

Im running my 4690k @ a nice stable 4.4 Ghz on an air cooler.

Ive got mine running with a gtx970 but when I first built it I had it running with my old 7950 and comparing it to my old FX8350 it was an upgrade and was far smoother in games and gained a nice increase in FPS in games.

I dont regret buying the 4690k and the FX8350 was a cracking CPU.

My oldest is running with an FX8350 at the moment with an Asus v formula z motherboard and yea its a great machine but I wouldn't be tempted to swap him boards and CPU's
