Raised price for 955+5850 build

So I've posted here a couple times over the past week or two about some builds. I was having problems cause I was trying to keep the price down, but after getting all my exam grades, I'm quite proud of my 4.0 for this semester, and decided to raise my budget and spoil myself:

APPROXIMATE PURCHASE DATE: in the next couple days

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Programming, watching tv on my 32" HDTV and gaming

PARTS NOT REQUIRED: mouse, keyboard, monitor, hdd, optical drive, os

PREFERRED WEBSITE(S) FOR PARTS: newegg.com / USA

PARTS PREFERENCES: AMD system

OVERCLOCKING: Yes SLI OR CROSSFIRE: I would like to have the option

MONITOR RESOLUTION: 1920x1080

ADDITIONAL COMMENTS: n/a

This is what I've come up with:
Cooler Master 690
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - 69.99 - $10 mir = 59.99

Corsair 650 watt psu
http://www.newegg.com/Product/Product.aspx?Item=N82E168... - 119.99 - $30 instant - $20 mir =69.99

955BE + Asus 5850 DirectCU - 159.99 + 339.99 - $30 instant = 469.98
http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...

Asus M4A87TD EVO + Patriot RAM 4gb - 109.99 + 129.99 - $20 instant = 219.98

Total after MIR: $819.94

Am I missing anything? Does anybody know of any compatibility issues, etc? Also, do you think the 955 is overkill, i.e. should I step down to a Phenom ii x3 720 w/ a nice cooler?
