Cheers for the quick reply! Just watched another digital foundry video again where they put the i5 OC against previous i7's (stock) and I find it impressively pulls ahead of them. I'm leaning more and more towards the i5-6600K myself as well. Hope you'll get your right together soon mate! And when you do, do tell how you like it.
There are only a few chips available here, and at a premium because of it. I'll wait.
What motherboard you'll get? Going for the Asus Maximus VIII Hero myself. Put some G.Skill Trident Z in too - of it becomes more available too, not many sell it and there seems to be little to no stock at the moment.
I suspect you won't notice the difference when gaming is your thing, compared to an i7, if some of the solid reviews are to be believed. Your GPU will be the single most important thing still. Do give the i5 a nice overclock though! I've never had an i5 either but think I'll be alright for some time to come.
He will with that CPU. That one part of Sandy iirc and is only a dual core. Upgrading to the newest quad core would really help push the TX further. Now if he upgraded from a quad core sandy to a Skylake quad core, the difference wouldn't be that noticeable but in Xfire/SLI it would help with frametimes- not enough to warrant an upgrade though.
That's what I meant, the difference between the i5 and i7 Skylake, not his current back up chip - I should have been more specific. I feared going from an i7 SB to an i5 SL would be a performance hit of sorts, but I've come back from that thought currently.
