The one thing I am unsure of, is the PSU. Now, I'm pretty sure that this will get the job done without issues, but is Corsair a good manufacturer of PSUs? If you have alternatives, please do let me know. Oh, and I prefer 1000W, since I will be running other mods for light and stuff, so I do need to have more than bare minimums. Also, I will be overclocking the system, so there's another reason to have more power than needed.

Second, I am just thinking about water cooling, but have NO idea what I'd need. I mean, I did read up on "Conundrum"'s post under this post:
http://www.tomshardware.com/forum/ [...] elp-needed
Which was helpful, but I guess I'm a slow learner? That, or it's really late and I need to read more? Or is it that I don't know much and don't want to choose a crappy part? Who knows, lol. I have never water cooled anything, but would like to start. Basically, what would I need to water cool JUST my CPU, and 2 4870x2 in CrossFireX? And, should I get something for any other part of the computer? I mean for water cooling.

Man... the more I look at the cost of this system, the more I think I don't want to buy it... lol. Thanks for reading and helping out! I appreciate it!

I should also note that I'm thinking of choosing a different Mobo. If that's the case, here it is:
Mobo - ASUS R.O.G. Crosshair III Formula ATX AM3 790FX/SB750
http://ncix.com/products/index.php [...] cture=ASUS

Choosing that mobo does allow me to cut the price down to $2507.64, so that's something that is good to note. (I do need optical audio, so that's why the first mobo had a sound card, this gets rid of it since it's basically the same thing)

You could spend half that and max out almost every game at 1920 x 1080 , and, as a bonus global warming would be delayed about 30 minutes

Well if you are doing quadfire in the future, you BETTER grab a 30" monitor. Anything less will just go to waste.

If you stay at 19x12 or below, one 4870x2 will be fine. If that's the case you can drop to a 750W PSU.

if you're spending that much on a PC then at least use an i7.

and WC isn't worth it, with newer CPU's, all you'll get are slightly lower temps and maybe an extra 200MHz on the CPU, making it over a $ per extra MHz.

lastly the 4870 X2 is not worth it in any way, since the 5870 comes out next month and will beat it for a lot less money and be a lot quieter.

You know, I was just reading up on some reviews on CPU's. I am and AMD fan, due to price/performance. You are, however, right. If I am spending that much cash, why not just go with a bit more power? Lol. I guess the mobo would be changed to a x58 something-or-other and the CPU would most likely be a i7 920 (I do have some price limit, lol).

I actually didn't know that WC isnt really worth it for newer CPU's, thanks for that! On a side note, I currently use a Zalman.. umm... I don't remember what it is, but it looks badass! haha

I guess I will need to wait for a bit, most likely the release of that AND windows 7. Thanks for the help!

I personally don't see it costing a lot less, but I don't see it costing more than another arm, lol.

I was using the zalman cooler on my old AM2 slot, just was stating that I have one. Thanks for all those tips though!

I do use 7.1, which is why I had to make sure. Well, I'm building a computer, and my friend is replicating it. So, I guess I could ultimately skimp on the stuff I don't have, which is the 7.1

Thanks for the tip, I'll check this stuff up when I wake up. I'm crazy tired, lol.

Thanks for all your help everyone!

The one place watercooling will help you is on the video card. You will see the temp drop literally in half of what it would run on air.

I am willing to spend around $700 for a water cooling system for all my components. Maybe a little, let's say $800 then. For CPU + 2 GPUs.

That's what I was hoping for. Maybe clock it up a little more just for... I guess bragging rights over my friends, lol.

I have a 1000W PSU I'm currently looking at, but I am willing to drop or increase the Watts if it would be a waste or not enough in the end. I'll be doing a lot of mods.

I've only ever built one computer, and it's the one I made around 5 or so years ago, lol. It was all air cooled, so I figured I'd try water now. Main thing I'm concerned about is, is it over all worth water cooling? helloworld_98 said for newer CPU's it isn't as much of an upgrade, but I do know for GPUs it's a huge upgrade, in the temp + noise levels, or lack thereof.
