Only the Quick Sync improvement seems like a reason to pick Ivy over Sandy. Although Thunderbolt use could be nice.
You'll be fine with a 2600k, I was in the same situation and opted for a 2700k that was on sale. Ivy is a tick iteration in intels business model of releasing CPU's. It is essentially a die shrinked sandy bridge CPU. You aren't missing a damn thing other than significantly more powerful igpu but who uses igpu if you're a gamer lol? The only forseeable problem I can see is in a year or two when the new GPU's come out you may find yourself hitting bottelenecks if you plan on SLI/ triple SLI especially but for now you are perfectly fine and imo it was a reasonable decision although I personally would have probably just stuck with a 3570k at this point.
Either way you will be happy and if you are a guy who prefers 1 single very strong GPU solution which is actually better if you enjoy competitive play because SLI introduces input lag anyways you'll be fine for 2-3 years I would say. I can't see a X16 PCI-E slot getting bottlenecked sooner than that.
In the future just be conscious that if you are planning on doing a strictly gaming rig than HT is completely unnecessary, however if you do things like photoshop, video encoding/editing etc etc. Things that actually benefit quite a bit from HT then go that way. However if you are 80% plus just gaming on your PC HT is really a waste of money largely I find. Don't always think 2600k>2500k or 3770k>3570k because for gaming that simply isn't the case ;p.
You will be perfectly find though so don't worry about it man, enjoy your new rig and have fun! That's what I would do
What this guy posted is largely a load of bologna, USB 3.0 is supported on the Z77 chipset natively, the CPU is irrelevant and anyone who is running faster ram is seeing MAYBE 2-3FPS difference in real world gaming scenarios, 1600MHZ is perfectly fine for gaming and should be for the forseeable future. Anyways Sandy can support up to 2400mhz iirc which will be plenty fast for quite a long time.
Forgive spelling/grammar/syntax error, i'm drinking and tired
EDIT: Actually if you look at the link he provided though you will see that ivy bridge is only slightly better, we are talking like <6%? According to those benchmarks, so don't sweat it!Edited by immakulate - 9/15/12 at 11:49pm
