First time builder looking for advice on a 700-900 gaming rig

Seeing as my six year old dell is dying before my eyes and a tax refund is in the mail, it's a perfect time for me to upgrade. I think I have most of the parts picked out but I'm sure this list can be optimized both for performance and money. Of course, Newegg sold out of my chosen mobo shortly after I picked one out; I wanted GIGABYTE GA-MA790GP-UD4H AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard - Retail instead but oh well. At least it'll save some money.

APPROXIMATE PURCHASE DATE: As soon as possible

BUDGET RANGE: $700-900 but I could be persuaded to go slightly higher for the right purchase.

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Games, Music, Movies

PARTS NOT REQUIRED: Monitor, Keyboard. Mouse and speakers will eventually upgrade but they work fine.

PREFERRED WEBSITE(S) FOR PARTS: No preference

PARTS PREFERENCES: No preference

OVERCLOCKING: Yes but first timer. SLI OR CROSSFIRE: I would eventually like to crossfire. Maybe in a year or so.

MONITOR RESOLUTION: 1920x1080

Comes out to $869.36 - $55mir including shipping.

Are there any glaring omissions or obvious changes? Are there any cords or brackets or anything that I'll need to order? Thank you.
