So I bought and built a computer who is now around 4 months old, here are the specs:
Z68 Extreme3 Gen3
Intel i5-2500k
Antec 520M PSU
Radeon HD 6870 1GB-GDRR5
G.Skill Sniper 8GB (2x4GB)
Seagate Barracuda 500GB (good enough, might get SSD also)
Thermaletake Chaser MK-1 (BEAST btw)
Periphs:
Asus 22"
Razer DeathAdder + Razer Goliathus speed edition pad
Microsoft keyboard (good enough for me, wouldn't upgrade till it breaks)
SteelSeries Siberia v2
When it comes to my goal, I'm just looking to have not the most high-end computer, but strong enough to run nearly all the games on med-high settings.
