I am building my 3rd computer and this one will be a super gaming computer. I have a $2000 to $3000 budget and want to all games on max settings. I will also would love this to be water cooled. I will post pics of my previous builds if you would like. I will be purchising this within one month.
 
Sincerely,
John

you can have my rig for 3k   lol

Evga X58 
I7 9XX (I dont think they sell 920s anymore but a 930 is the same thing)
6GB OCz Triple Channel DDR3 RAM (1600mhz at least)
EVGA GTX580 (You could really get 2 or 3 of these with your budget)
HAF 932 (great case, lots of room)
WD 1TB HDD
SSD or Raptor Drive for boot
1200w PSU from a reputable brand (Do they make 1600w?)
As for WC, i dont really know for sure so i wont speculate.
 
You can really go either way on a lot of those parts and just choose which ones you like as far as color or w/e. I wont find part and part numbers for you since i think you should build the computer, and just ask us any questions you have. Makes it much more fun building and a more involved experience then the forum just voting on the best build and you buying the parts. Using the little list of parts i gave you youll be able to make a great computer for around 1000-1500 and youll save a Ton of money. 
 
But wow, for 3G, you could easily get a triple monitor set up with SLI GTX580. you can get whatever intel I7 chip as long as its in the 200-300 range. any of the $500+ ones are a waste of money imo since you can OC to those speeds with 0 risk on your system. 
 
Just remember to stay with reputable brands like ASUS, OCz, EVGA, Cooler Master, and away from brands like Sparkle, ASrock, intel brand mobos, Biostar, and others.

Wait for Bulldozer or Ivy Bridge.

the 932 is a great case but targeted more at air cooling, i hear the 800d is a great case for water cooling since you can fit a 120.3 radiator in it.
 
also i think the p67 overclocked might indeed be a better setup since even the "bad" chips still tend to hit near 4.5ghz especially if your water cooling
 
but as some others have pointed out waiting for the next gen of chips would be ideal.
 
a pair of 580 classifieds should over clock like beasts and give you more then enough muscle for gaming. if you want to go with a multi monitor setup you need to consider the vram on the cards as well since for a surround gaming setup you would want to get the ones with 2-3gb of vram (dont remember what they have 3gb i think)

Case is up to him. Choose what looks good and performs well. Ill agree though the 800D is better for WC. 

And idk about the i7 2600k. I prefer the X58 and i7 900 series. I bought the 920 a while back and i dont even see it bottlenecking any time soon. 

that is true and my x58 setup is still quite acceptable for me as well, very glad i bought it.
 
either setup would allow for great performance in gaming, i was just remembering some of the numbers people were posting on the p67 as far as vantage goes.
 
if you think you will end up with more then 2 GPUs though then i would lean towards x58

I love the 800d and will go with that. As for mobo and processor, I like x58 and have heard it can run a xeon processor. Is this true?

certainly but keep in mind that the xeon line is more or less the same as the i7 line, although my understanding is that if you get the i7 930 equivalent in a xeon its like getting a binned i7 so by getting an i7 you wont necessarily get any worse performance, or have any less overclocking potential.
 
check out microcenter if you can they are selling the 930/950 very cheap right now.

How is the 960 vs the 990x? If I overclocked the 960 enough would it out perform a non overclocked 990x?

I haven't looked at benchmarks comparing these too but i would guess that a 960 could if you are not using an application that can take advantage of the extra cores/threads of the 990x
 
and someone please correct me if i'm wrong but i don't think many games are coded to really make use of that many threads yet.

I am leaning twards the 960. For the mobo, I have a evga 4 way sli that I purchased a while back but how would I make it fit into the 800d?

What is a good graphics setup that will max out all games out + the ones that will be realesed withen the next year?

2 580s or 3 570? On the 580s 1.5gb or 3gb?

I 100% agree. The one watercooling rig I did(my mods rigs) the watercooling cost almost 500$ I am aware that watercooling is expensive so I did not include it in the price. I have a 1200$ budget for the watercooling.

what is the performance diffrence between 2 1.5gb 580s and 2 3gb 580s?

For gaming I will only be using 1 monitor

On ocasion I will put up to 2 more screens for multitasking(nothing much) So would I benifit from the 3gb?

I will go with the 1.5gb version.
I found this case and it looks good but I need more imput
