I7 System - Handful of Questions, Doublecheck the Build

My five-year-old desktop died spectacularly, so I've taken that as a sign that I need a new one. I haven't built a new system since the old desktop. So I'm quite rusty on all the new developments of the past few years and would like to get some feedback on my selection, or at least a second set of eyes to make sure I didn't overlook anything important. I would like to build a system that will give me a solid 4-5 years of life with upgrades along the way.

APPROXIMATE PURCHASE DATE: Somewhere in the next two weeks. BUDGET RANGE: $1,600

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: A little bit of everything -- graphic design, multimedia (movies, music, etc. I don't own a TV), gaming, internet and home office work (I assume pretty much anything can do the last item these days).

PARTS NOT REQUIRED: Keyboard, Speakers, Mouse, OS.

PREFERRED WEBSITE(S) FOR PARTS: newegg.com

PARTS PREFERENCES: I prefer ASUS Motherboards and the i7 CPU.

OVERCLOCKING: Maybe, I would like to look into overclocking the system as it ages, but probably not on the initial build. SLI OR CROSSFIRE: Yes -- again, not on the initial build, I'm looking at the possibility of the second GPU when price drops / it becomes necessary to keep up with the games.

MONITOR RESOLUTION: 1920x1200

ADDITIONAL COMMENTS: My last desktop sounded like a vacuum cleaner most of the time. I'd like something quieter this time around.

The current components that I'm looking at:

Okay, I promised questions:

(1) Simple Question: Have I missed anything? Have I picked out components that are compatible with one another?

(2) Will the stock fans, heatsinks, &c. that come with the case and CPU be sufficient to keep this system cool or will I need to look for additional cooling components?

(3) I have gone over budget by almost $300. I am wondering if it would be a good idea to try to skim the cost down in a few places. The possible cuts could be: RAM (either less, or a different type could drop the price by $100), the case (I've had bad experiences with cheap cases in the past -- and a lot of the slightly cheaper cases look gaudy with window panels &c), different video card, or different monitor (see 4). Would one of these be a good place to cut back, or should I just bite the extra expense?

(4) This is a two part question. (a) I've spent a long time trying to find a monitor that has good reviews for both graphic work, gaming, and is in my price range. Does anyone have any good experience with this monitor, or suggest alternative monitors that suit this combination of needs? (b) Atop this, I want a monitor that will function both as a desktop monitor and as a television for the purposes of hooking up game consoles. I've been assuming that a monitor with component or composite video input will work with my old game consoles (namely the playstation 2), but I've yet to read of anyone using their monitors for such. Have I assumed correctly that composite/component input means I can hook my old devices to the monitor?

Thanks. Lurk boards like these and I start to notice everyone throwing extra coolers on their systems . . . good to hear that's an extra cost I won't need (for now).

As for the monitor. There just doesn't appear to be many monitors out there that match what I'm looking for. Once you add on the composite/component inputs (which seem to only appear on 24+" monitors it seems) the manufacturers add an extra hundred or two onto the price tag. Still, seems cheaper than buying a monitor and a television (again, assuming I can use it to double for both).

^ he doesn't need a 900w psu if he's going with that case, 900w is what you need for three 4870's and they're not going to be cooled enough in that case.

IMO that mobo is unnecessary.

As for the GTX 275.. Eh.. I don't know. CF two 4770's instead?
