Upgrading my PC to 4 Box better

Hello

I´ve been 4 Boxing fair a bit in Diablo 3 Vanilla. Now with the expansion i plan on doing it again. THe problem now is just my Hardware. I used to only get around 15-20 FPS on my main (and i went through alot of settings).

MY System atm

AMD Phenom II X6 1090T
XFX Radeon HD 6870 925M
Gigabyte GA-870A-USB3
Corsair Vengeance DIMM Kit 16GB, DDR3-1600, CL9-9-9-24
Samsung SSD 840 PRO 256GB

What do you think is the Bottleneck here?

Planned Upgrades

Gigabyte GA-H87-HD3
Radeon R9 270X
Intel Xeon E3-1230 v3, 4x 3.30GHz, Sockel-1150, boxed (???)


Not 100% sure about the CPU though. Is it really neccessary to upgrade to a "4930K"?

You can tell for certain where your bottleneck is: HOWTO: Tweak your framerate, Identifying framerate bottlenecks

I'd guess your 6-core CPU is probably enough.

My impression is that D3 needs significantly more resources since ROS was launched. Perhaps Blizzard will optimize it again at some point but at the moment I see many performance issues in different forums.
