Title says it all. I have a rig which is a non k i5 760 (2.8 ghz), in which i have upgraded the gpu to a 7870XT and have overclocked the gpu to 7950 performance levels (1200 core clock, 1500 memory clock). It it worth upgrading the CPU and mobo to a new haswell I5 and will i see significantly improved performance in games?

(rest of the PC is 8Gb ram, 120 gb ssd, asus xonar sound card, 500w silverstone psu)

yes it will bottleneck in new games though,but for most games it will be fine.upgrade to haswell ' i5 would be worthwile updgrade

Why don't you OC your i5 760?!! I have mine at 3.4 GHz at STOCK voltage (no need for exotic cooling). You can get it to 3.8 GHz with just a little bit of overvolting (although a big-air cooler would be helpful).
I'm running a OCed 7950 (1000/1450 MHz) and there is zero bottlenecking.

It is the non k version and I only have the stock cooler.

lol it is first generation cpus which have already unlocked multipliers so you can oc any cpu.

k series is only in sandy and ivy bridge cpus

you need to get cm cooler hyper evo 212 to oc

Can I boost it slightly without a custom cooler?

only around 100-200mhz more,but i suggest to get aftermarket cooler,they are very cheap less than $30

You are joking right? You can OC a i5 760 by at least 600 MHz on the stock cooler, and only get to 65-70 C at 100% load (and those are completely safe thermals). Mine won't go above 50 with a CM Hyper 212+ @3.4GHz.

^ buddy oc on stock cooler are never reccommended by any computer geek.it is not advisable.stock cooler is made for handling cpu at stock speed.

That is total BS. If you can OC your CPU with the stock cooler and stay within reasonable thermals there no reason not to do it. Of course you need to keep an eye on the temps... but you do that when OCing regardless (even if you have the biggest air cooler ever conceived).

you a point regarding temps is right,no offence

a 100-300mhz oc will not affect temp that much. but i bet you oc to 600mhz or more temps will be high @stock cooler

It depends of course on what you consider to be "high". I set the voltage to be fixed at 1.1V for my i5 760, then OCed it to 3.4 GHz (turbo still enabled). With the stock cooler, it would peak at 70ish C at 100% load - and ~65 for typical real-world workloads. That is not ridiculously high, and will not fry the CPU (it would peak to ~55 C at stock clock speed on the stock cooler). The key in my particular case was not allowing the mobo (a Gigabyte board) to automatically overvolt the CPU in accordance with my OC settings - that blew the temps to the moon. My i5 760 OCs to 3.4 GHz with no overvolting whatsoever, and it consequently doesn't get all that hot.
