A few months ago the graphics card on my HP dv9700 laptop died. The VGA backup on it works, so I am able to use this laptop to write this, I just cannot play video games

Also, I have been wanting to build a new desktop to replace my 6 year old Dell.
Edit: First first, price range is $1,000 to $2,000. And I want to do it right, not half-arse it.
So, first, I think I shall go with Intel, unless someone can make a very persuasive argument for AMD.
Second, I think I have decided upon going with the Intel x58 Motherboard and the i7 920 processor (again, unless someone can make a great argument otherwise. I doubt that there is a need for the 930, 940 or 950, since by the time I would need their higher Ghz, I could just buy the 970, 980 or even 990). Where I am having trouble deciding is, what brand to go with for the motherboard?
I have read good things about the Gigabyte GA-X58A-UD3R, until I read about a defect that caused an annoying noise. However, that problem seems to have been fixed with the latest update.
Apparently there are more expensive models of the Gigabyte x58, but from the reviews I read, apparently you do not get much more for the big price increase (from $120 to $180 more), which is one of the reasons the UD3R was so well liked. The UD3R can be had for as low as $209 on Newegg.com
Now, for $370, the Asus Rampage 3 Extreme does very nice (I noticed that the Gigabyte was missing some features that an MSI had, which bothered me, such as the Gigabyte not stating that it supported i7 Extreme processors, which I may want to upgrade to when their prices drop to that of the 920).
I would very much appreciate any input

Some further questions:
Do you anticipate a price drop or new essential technology anytime soon such that I should wait a month or two before buying the parts to make sure I build a future-ready PC (I am busy enough playing CoD: Black Ops on my 360, and the 7 hero/embark update has not come out yet, so I do not really need a new desktop just yet)
I doubt figuring out what RAM or other stuff I need will be too difficult, however, it would definitely help to have some suggestions for the:
Sound Card
Graphics Card
A great Case
Speaker/Sound system
etc
Gaming Keyboard
Cooling Unit (I have no idea about this, so need lots of help with this)
Power Supply (same as cooling unit)
Anything else I missed.
I have the mouse I want, and a TV I use as my monitor.
Whelp, have at it

Edit: Also, apparently the Asus Rampage 3 can accept up to 4 GPUs, I do not know how many the Gigabyte can take. Thoughts?
