Would you recommend changing anything? note: I already have a HDD and SDD so no worries on that.
AsRock Z77 Extreme3 Motherboard
i5-3570k Intel processor
CM HAF 922 Case
HD Radeon 7950 Gigabyte GPU
Cooler Master Hyper 212 EVO or Corsair H100 (great sale right now)
G.Skill RipJaws X Series 2 x 4 GB
Corsair HX Series 750w PSU
Yes, I know its more that 1000$ but I'm buying thins when they're on sale to keep the cost down.
More about1000 silent gaming
This is pretty much the exact layout I'm planning on getting, except I'm going with a coolmaster extreme case, and a GTX 670 instead of the ATI. Oh, and 8GB RAM instead of 16. Currently, for gaming, anything over 8 is a waste, but go for it!
