A couple things. One, do you plan to overclock? if so, I'm sure you know the 2500k is the way to go. If not, why not drop down to the 2400? cheaper, same processor really.
Also, substitute that 6850 for a Sapphire 5850. It's better, cheaper, and smaller.
Also, that hyper 212+ can be found on amazon for $30.
All looks good. Here are some things you might consider if you haven't already: the Sapphire HD 5850 for more raw power than the HD 6850 at a lower price, Also the OCZ fatal1ty 550w for more amps across the 12v if you do the watts/12v=amps (antec 444w/12v=37amps shared OCZ 450w/12v=37.5amps shared).
From what I understand 60hz is the basic refresh rate for all LCD monitors. I plan on buying that exact same monitor because its ASUS and its HD for only $150. Can't beat that. Has nothing but great reviews on NewEgg.
