Grem
SuperG
It's all marketing, poser-ing, and toll collection via the i(take a 30% cut)Store.
LOL!!
On topic: I also use the i7 2600K.
I can use 4-5 instances of GR5, several instances of True Piano, Dim Pro, ezDrummer, and/or BFD Eco, and I'm using the power of the CPU, but it's not maxed out.
I run an i7 2600k @4.6GHz,and got the heads up yesterday, from Scott at ADK,that the i7 3770k @4.5 is identical in performance,and there is no real advantage to Ivy over Sandy,in amounts of plugins at various buffers,and audio in general.....Socket 2011 however is the platform that will be around for a while yet,as Ivy E [2013 Q2/3?] will also be running the 2011 socket.
The 2600k/3770k are socket 1155,for which Ivy,maybe the last new models for that platform.
Scotts Benchmarks
http://www.adkproaudio.com/benchmarks.cfm pretty much show all of this,but one surprise is how overrated Dual E5-26xx are as an advantage for audio,as in not much...pretty interesting,compared to sites like Passmark,which make a 3770 look twice the power of the cool n stable OC'ed 2600k.
