If you're wanting a top of the line system that you can overclock to your hearts desire and get the best of everything on, I'll post it below. However, the motherboards and processor of today will be "outdated" in about 4-5 months considering Intel's new "Ivy Bridge" line is coming then. With a new series of processors usually comes a new socket, which means new mobos and new chipsets. But this build will get you what you need and want.
Assorted peripherals: You can get any keyboard/mouse/speakers/etc.. with the leftover budget, they're totally preference and what feels best to you.
Total (Not including peripherals): $2,457.31
**Note: I did not include SLI with this build as you really do not need to SLI the 580 or 590 GPU's. I highly recommend you get one to begin with and if later a game comes out that really pushes these cards, grab a second. The only reason I could see you needing two is if you run on a VERY high resolution (2500+) with AA on etc.. However, I included a 1200W power supply in case you do decide to SLI later, it will handle it.
If you never plan to go Quad SLI/CF bump down to the ASRock Extreme3 Gen3 ($125 and supports 2-Way SLI/CF)
You can also knock down the the CPU to an i5 2500k (best bang for you buck CPU) or even i5 2400 (if you plan not to OC)
Drop the HDD down to a 1TB ($130) (if you are military like i assume you are, you should probably have a crap load of movies and music like i)
The GPU I selected has been praised all over the web for its quietness compared to the others but you can always lower it down to a regular $500 version if you want (you can SLI another one later down the line right now its way over kill for just one 1080 screen, )
You can also drop the card reader if you want (dont know about you but even im paying 2k+ for a rig I want it to be able to do everything I need it and I take lots of pictures)
You can also drop the BR player to a regular DVD drive if you want ($20)
I'll let you choose your mouse, keyboard, and headset cause its all about what you like and how it feels
Also I put in a complete water cooling system for the CPU, if you dont plan to OC drop it as well, if you dont want to mess with water cooling go for the CM 612
To Emelth, that's a great set up. I will probably go SLI(no more than two) later, but as you said one gtx580 will do the trick for now. If I do go with SLI later, will I need to upgrade that processor? Also, I'm not sure if I'll need to OC.
