I just wanna show you my PC Hardware. I am using this PC fpr Gaming and 3D Modelling. It works pretty well:
Mainboard: Gigabyte GA-970A-UD3P (AM3 +)
CPU: AMD FX-8350 Eight-Core
GPU: AMD Radeon R9 280X His IceQ
CPU Fan: Corsair H80i
HDD: Western Digital Blue 1TB
Case: Thermaltake Urban S31
Mouse: Razer Mamba

I play new games like Shadow of Mordor with 40-100 FPS. Very good I think.
