With the upcoming game Rome 2 TW, I'd like to max out that beauty so I decided to donate my current PC to the family and buy a new one, building it myself.

I've managed to come up with this but I'm quite the novice, and would like it if anyone could lend some advice and confirm whether or not my rig is compatible/decent.

So far, this;

- Asus P8Z77-V PRO Motherboard (Socket 1155, 32GB DDR3 Support, ATX, Wifi, Intel Z77 Express, Network iControl, USB 3.0, SLI/CrossFireX Support)

- i5-3570K CPU (4 x 3.40GHz, Ivy Bridge, Socket 1155, 6Mb L3 Cache, Intel Turbo Boost Technology 2.0). I do plan to Overclock also.

- Cooler Master Hyper 212 EVO (120mm)

- MSI N780-3GD5 Nvidia GTX 780 3GB GDDR5 PCI-Express Graphics Card

- Corsair 16GB 1600MHz CL10 DDR3 Vengeance Memory Kit

- Corsair CX750 Builder Series CX 750W ATX/EPS 80 PLUS Bronze PSU

- Samsung 840 Series 250GB 2.5 inch SATA Solid State Drive

- Western Digital Black - 3.5 inch 1TB Desktop SATA Hard Drive - OEM

- Case - NZXT Phantom USB 3.0 Big Tower Chassis - White

- Microsoft Windows 7 Home Premium with Service Pack 1, 64-bit

- Asus DRW-24B5ST 24x Internal SATA DVD Drive

Opinions and ideas are most welcome,

Thank you.

What OS system do you suggest please? Thank you!
