First Build - Much Advice Wanted

Help me Obi-Tom Kenobi, you're my only hope.

APPROXIMATE PURCHASE DATE: Next 7 Days
BUDGET RANGE: US$1500, but I'm married, so in the interest of having relations again less is more.

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: gaming, surfing the internet, watching movies.

Specifically interested in a system that will kick this game's ass:
http://pc.ign.com/dor/objects/1895 [...] 70809.html

Since it's not out yet, future proofing is absolutely necessary.

PARTS NOT REQUIRED: Monitor (running a 17" Samsung I've had for 2-3 years, will consider upgrading when the game above comes out. Would be nice to play on my 40" LCD, but since I'm married I wouldn't be able to enjoy a game on it without hearing how no one else can watch TV. Also, I imagine I don't have the graphics buget to support such an endeavor).

PREFERRED WEBSITE(S) FOR PARTS: newegg.com (would prefer to single source this build to minimize shipping costs).

PARTS PREFERENCES: I don't know what's good and what's sketchy, help a guy out on that.

OVERCLOCKING: Yes
SLI OR CROSSFIRE: Maybe

MONITOR RESOLUTION: 1280x1024 (MUCH higher if I want to use the 40" LCD, but again don't want to spend X-box money for a graphics card, prices still amaze me)

ADDITIONAL COMMENTS: I've never built my own system before. Looking for advice on getting more performance for the price, or the same performance for less money.

I know I could save money on the case, but I love the way this one looks. Classy. Unless it has cooling problems, I'm pretty set on it.

Components Planned (Subject to change based on the TH gurus comments):

Graphics Card: HELP, I have no idea. I'm an electrical engineer, thought I was smart, but the more I read on graphics the more confused I get. 95% of my play would be on a 17" monitor, so high resolutions aren't a big deal...yet. Playing on the 40" LCD would be fun, but between the nagging wife and the sticker shock on GTX295 and multi card setups, I'm not sure what to do. Single now, add another later? Grrr....maybe I should stick to the Wii.

I'll also need thermal paste, and probably should get an antistatic mat and wrist strap since I can't build this at work. Are there any other tools/accessories I'll need to build it myself?

I have XP, but know I need to move on to use the RAM and latest DX. When will 7 be released? Am I best off trying to buy Vista with the free upgrade to 7?

Brands to avoid like the plague? Brands worth paying an extra few bucks for?

Any parts suggestions or help in educating someone about to drop 2 weeks pay on personal funstation is greatly appreciated.

Add a second XFX HD 4890, when you get additonal money or once the price drops with DX11 cards and you'll be set for a while!! or drop the Hanns-G monitor and add the second XFX HD 4890 and run it on your 40" TV. I would go with the Hanns-G so you don't get into trouble with the wife on no one can watch TV... I'm married as well... so I understand!!

These are just some of my suggestions...

Good luck with the build!!

Okay... i7 920 it is than.

Additional Recommendations:
1.)Change your case to Cooler Master RC-690. It is very similar case for $100 less.
2.) Get the Xigmatek Dark Knight I listed above. The Xigmatek has better cooling performance for less money.
3.) Get the WD 640GB Black, it is faster then the 1TB Black. If you need a TB, get the one you picked. You have me confussed on the two smaller HDD comment? I think I listed just one hard drive but maybe I said two???
4.) Get the XFX HD4890 GPU for your system, specially if you buy the Hanns-G monitor. If you aren't getting the 27 monitor, get the EVGA GTX 260 Core 216 that is on sale now on Newegg.

The 750 Corsair PSU is plenty for your system. I listed the 850w PSU to give you a little more upgrade room for your PSU.

The RPM is a factor in how "fast" the hdd is, but more than that is the cache size. I didn't have time to look up the two hdds that you are talking about but i assume that the cache size is what's making the difference.

I would go:

pick a case and 600w+ psu you like

gigabyte x58-ud3r
core i7 920 (if your not overclocking, the stock cooler is fine, if you are pick a cooler based on reviews+price)
6gb of ddr3 (again look for a deal)
I would get 2x WD 1TB black and run them in raid-0 on the intel ich10r (your fastest option on a budget)

videocard, go for a 9800gt 512mb or higher, if your not gaming, this will do just fine

This is headed in the right direction but sort of off the mark. In this case, the 640 should be slower because it has a lower aerial density (320<333). Higher aerial density almost always translates into higher sustained read/write speeds, and this holds true for the WD Black editions as well. They lose in sustained read/write to higher density Seagate drives, for example, but often have faster seeks.
