$800 gaming rig

[zookoid]

Hi everyone, first time poster here. I'm looking for some advice on compatibility and price effectiveness of the build I'm setting up for gaming.

Approximate Purchase Date: this week

Budget Range: $800-$900

System Usage from Most to Least Important: gaming. I intend on playing Battlefield 3 and SWTOR.

Parts Not Required: monitor, keyboard, mouse, hard drive, OS, speakers

Preferred Website(s) for Parts: newegg.com

Country of Origin: United States

Parts Preferences: Intel cpu, asrock mobo, inwin case

Overclocking: Yes

SLI or Crossfire: Maybe

Monitor Resolution: 1920x1080

Additional Comments: basically I would like to rest assured that the parts I've selected are compatible and not cheaper from other sources, or have alternatives that could be more efficient, future-proof or cost effective. Also, If I crossfire 6870s, would I need a bigger PSU?

To start with if you have any intentions of crossfire then you should get a bigger PSU.

High Current Pro HCP-850 850W TX12V v2.3 / EPS12V v2.92 SLI Certified CrossFire Certified 80 PLUS GOLD Certified Modular Active PFC Power Supply $149.99 and a $30 rebate , plus free shipping.

The only reason I am suggesting this one is because it is on sale with free shipping , so you could get an 850w power supply for $119.99. Also be advised that on that motherboard the third Pci-e slot is only a X4 slot and if you use both of the others in crossfire or sli they drop down to X8.
