I received my new I7-4770K and Asus Z87-Pro yesterday to replace my I5-2500k and Asus P8Z68 V-Pro. I installed all the new parts this afternoon without any problems then used the AI Suite 3 to "Fast Optimize" overclock. It overclocked to a very stable 4.25GHz (125MHz x 34 @ 1.2V Core)
I have already seen a big improvement in 3D rendering in Revit. I have attached a few pics where I rendered the same 244MB 3D BIM model with the I5-2500K and I7-4770K with quality settings on Medium, High and Best. Below are the differences in rendering times:
I5 - Med - 00:57 --- I7 - Med - 00:39
I5 - High - 02:01 --- I7 - High - 01:16
I5 - Best - 06:43 --- I7 - Best - 04:00
I still have the AMD FirePro V4800 installed but will run another benchmark when I receive my NVidea Quatro K4000. I will also rerun the benchmarks on my SSDs to see if there are improvements on the SATA3 ports on the new Z87-Pro motherboard.
