I build this machine for gaming, web programing and multimedia work. Run perfectly, maybe in near future I will increase RAM to 32 GB (just for fun) and change my 2 video cards for something more powerfull like an MSI Radeon HD R9 290X or Nvidia GTX 980.
I install Windows 7, waiting for Windows 10. This machine starts the OS in less than 10 seconds and reboot in less than 15 sec.
I play games with this machine like Battefield 4 Premium Edition with high presets and go very well.
All pieces and parts were bought in Mexico Online Store - Linio, maybe I spend 200 USD more than if bought in USA.
NOTE: Sorry my bad english but spanish is my native language.
