overclocking an intel core i7-860 for gaming

Hi,

A friend of mine has an aging system with an i7-860 combined with a Radeon HD 5770 on an Asus P55 chipset motherboard and obviously, this doesn't cut it anymore for gaming. As I have recently built my own pc, I have gained some hardware experience and would like to help him with upgrading his system. He's going to need a better graphics card, but with a more high-end one, his CPU will probably end up bottlenecking during gaming. Therefore I'm planning on getting a Hyper 212 Evo and overclock his processor. I'm thinking about 21x160MHz, because his RAM is DDR3-1600 (even though his CPU doesn't support 1600 out of the box) and this would make it possible to run the RAM at 1600MHz and get the processor up to 3.36 GHz, a pretty minor overclock but still a respectable speed and it will probably work at stock voltage.

Would that be a good overclock and would it be sufficient to run a GTX 760/770?
 
Solution
3.3 GHz should be sufficient enough to run a GTX 770; however, if the motherboard only runs PCI-E 2.0, then the GPU will not run at its full potential. Upgrading to a new motherboard and current-gen CPU should resolve the motherboard bottlenecking issue and give the new GPU a PCI-E 3.0 platform to run on. I went from an i7-950 to an i7-4790k with my GPU now running on PCI-E 3.0 and my WEI graphics scores improved because of it. Also, a Haswell "Devil's Canyon" CPU will trash a Lynnfield CPU in single-core performance.

Thanks for the reply. I agree that getting a new motherboard and CPU would be the best option here, but we're trying to get the best possible performance for as little cash as possible. We would be looking at €250-300 to get a new mobo+CPU and then some to get a GPU. That's cash he doesn't want to spend, so I think we'll stay with a GPU upgrade for now. If the rest would ever be upgraded, that GPU could then be taken along.

with a water cooler you could easily clock that prosseror to 4GHz and put an AMD R9 280x graphics card in it for well under your budget and you will have a great gaming system.
