I'd scope out this monitor, and yes, get it from amazon their return policy on them is amazing (and its free shipping). If any pxls are burned out or stuck, they will replace or refund it for you, where as with newegg I think it is 3 (it may be 5, cant remember).

, That is the monitor I recently upgraded my gaming rig too. Absolutely no ghosting and it handles blu-rays awesome
Also, I did not see any speakers, so I am going to propose the Logitech Z-2300's. I swear for the price I will never go to anything else lol (seems I plug these anywhere I can, but I really do love them).

I would wait and get everybody elses opinion first, as in the last two days alone (the two days I have been really active here) I have had to be corrected or contradicted on at least four separate occasions. That said, from what I can tell, if what you are asking is will everything work together, from what I see, it will all be compatible.
On a personal note, I am so friggen jealous of you right now, that thing will be beast.
A bit unrelated, but at the same time relevant, what do you guys think the power draw (In watts, don't care about amps yet, one step at a time as I need to get this sorted out first lol) this system will draw, seeing as how I recently found I over-guesstimate by more than I thought (apparently over by about 200 watts) I have taken to a little more subtle approach by using a fancy calculator. The numbers ended up working to ~590watts (with the OC'g) with the system running at 90%, does this seem correct? I really need to figure out this power supply thing lol. (590 watts is actually almost exactly 200 watts below my guess in the beginning of 800 watts, so that may be reasonable lol)
