Well first off I have never built one before, but I know quite a bit about comps so I think it should be fairly easy. I am doing all of my ordering from but I would like to have people look over this build just to make sure i'm not missing somthing thanks!

I am planning on putting windows 7 in it.

And as far as the hard drives I am thinking about getting 4 of them (as far as I can tell the mother board will support it) and having two of them paired so it would write faster and the other two mirroring the first two so I can protect my data from crashes.

Anyways your thoughts would be great thanks!

First off, none of your links work :ouch: 

What will this PC be used for?

You'd be better off with the I7 920 and overclocking it to I7 950 speeds and beyond, would cost a lot less too. Also, don't get an Intel mobo, Asus/Gigabyte or even MSI would be better.

1366 mobo's have a triple channel memory controller so it will work best with either 6GB or 12GB. You probably won't need 12 so stick to 6.

A 750W PSU will be enough even with two 5870's running on crossfire.

The Samsung Spinpoint F3 500GB is faster and I think it's cheaper too.

^+1 ... Build's comments!

Build missed ONE MAJOR issue!! The motherboard the OP listed is for the Socket 1156 and the CPU is for the Socket 1366... which won't work together!!!!

I recommend purchasing either the i7 860 and the ASUS EVO motherboard or the I7 920 and the ASUS P6TD motherboard.

Lol my bad, I'm half asleep :lol:

You haven't told us what you're gonna use the PC for. Unless your gonna do a lot of heavy multi-tasking (and I mean a lot), 12GB is way overkill. You'd be better off with 6GB of faster RAM and preferably with tighter timings.

I'll be using the computer for my "every day stuff"

Have World of warcraft running, simcity4 running, photoshop, probably 4 web pages with multi tabs. virus scanner in the background + whatever downloads/updates I want to do.

I chose the 12 gig because it was actually cheaper then the 8 I original figured in. Price is really no object, but I would like a fast system.
October 26, 2009 7:21:11 PM

6GB will be plenty. I could do all that with my current system which has 4GB RAM :lol: 

The one obsidian suggested looks good.
October 26, 2009 7:30:52 PM

The problem with the system/deal obsidian suggested is its only 2.66GHz. And I don't want to do any OC.
October 26, 2009 7:33:02 PM

2,66 on an i7 is plenty for yrs to come
October 26, 2009 7:42:10 PM

..Hmmm well my father in law just bought a Dell XPS 3.0Ghz (granted its not i7 tech) and it has 4 gigs of ram 1TB hard drive...and to be honest the thing is slow as heck.

Takes a fair amount of time to load. and struggles with newer games (SC4 with graphics on full, crysis with graphics low-meduim)

Sooo... yeah is the i7 really that much better?
October 26, 2009 7:54:44 PM

an i7 much faster then anything before
October 26, 2009 7:55:15 PM

Having problems with games would likely be a GPU issue, not a CPU issue. Load time is possibly an HDD issue.

Yes a 2.66 i7 will outperform a 3GHz AMD CPU. An i7 will overclock to possibly over 4GHz on a good $30-45 cpu heatsink/fan so why would you not get that free performance boost, especially with that massive overkill of a power supply?

If I am not mistaken, the Caviar Black 500MB runs two 250MB platters which makes it a slower hard drive than the Samsung F3 with a single 500MB platter or even the Caviar black 640 with two 320MB platters. The combination of 4 drives you are talking about is called Raid 10.

I beleive you mean GB when talking about the HD? And thank you for explaining the diffrence from teh samsung and the WD HD.

And as far as the overclocking, honestly? I wouldn't want to void the manufature warrenty, and I dont' feel I know enough to start OC.

I'll probably build this first machine to learn my way around, and then in a couple years worry about OC and all of that.

sounds like a plan
October 26, 2009 8:11:40 PM

So after reading through the WIKI about raids (which was very informative, thanks!) How difficult is it to do what I want witht he harddrives?
October 26, 2009 8:20:18 PM

I have never done raid, though most motherboards now have raid capability. There isnt enough speed increase in gaming to make it worthwhile to me.

Yeah I meant GB, thanks.

Does overclocking without increasing the voltage void the warranty? The intel i series is easy to overclock, some of the motherboards will even do it for you. I doubt many people building their own machine would buy one without getting a decent aftermarket cooler and at least overclocking up until it needs a voltage increase. There are some guides and advice in the overclocking forum. Do get your system up and running stable for a week before you start playing with overclocking, then just take it slow and bump up small steps.
