Making a new computer and need help

I guess I should start off by saying I'm new here, as I'm sure my posts will indicate! Rather than making small talk, I'll get right down to it. I'm building myself a new computer, and most likely my friends will just build what I build, because they're a bunch of lazy... let's just say people. Anyways, price isn't TO big of an issue, and I can hold off on building this computer if new technology is coming out soon. So far I've come up with 3 builds.

Build one:
CPU = Intel Core i7 950 Quad Core Processor LGA1366 3.06GHZ
http://ncix.com/products/index.php [...] ture=Intel
Mobo = Gigabyte GA-EX58-DS4 ATX LGA1366 X58 DDR3
http://ncix.com/products/index.php [...] e=Gigabyte
Ram = OCZ Gold OCZ3G1600LV6GK 6GB DDR3 3X2GB DDR3-1600 (times 2)
http://ncix.com/products/index.php [...] Technology
Video Card = PNY GeForce GTX 295 Single Pcb 576MHZ 1792MB 2.016GHZ
http://ncix.com/products/index.php [...] gies%20Inc

That comes out to AROUND $1850. I'm Canadian, don't make fun of my Monopoly money! Haha.

Build two:
CPU = AMD Phenom II X4 955 Black Edition Quad Core Processor AM3 3.2GHZ
http://ncix.com/products/index.php [...] acture=AMD
Mobo = ASUS M4A79T Deluxe AM3 ATX DDR3 790FX
http://ncix.com/products/index.php [...] cture=ASUS
Ram = OCZ OCZ3RPR16004GK Reaper 4GB 2X2GB DDR3-1600 (times 2)
http://ncix.com/products/index.php [...] Technology
Video Card = XFX Radeon HD 4870 X2 750MHZ 2GB 3.6GHZ (times 2)
http://ncix.com/products/?sku=3610 [...] acture=XFX

That comes out to AROUND $1600.

Build three:
CPU = AMD Phenom II X4 955 Black Edition Quad Core Processor AM3 3.2GHZ
http://ncix.com/products/index.php [...] acture=AMD
Mobo = ASUS R.O.G. Crosshair III Formula ATX AM3 790FX/SB750
http://ncix.com/products/index.php [...] cture=ASUS
Ram = OCZ OCZ3RPR16004GK Reaper 4GB 2X2GB DDR3-1600 (times 2)
http://ncix.com/products/index.php [...] Technology
Video Card = Powercolor Radeon HD 4890 PCS+ 1GB 950MHZ 1GB 4.2GHZ (times 2)
http://ncix.com/products/index.php [...] PowerColor
Sound Card = Creative Labs Sound Blaster X-FI Titanium FATAL1TY Champion
http://ncix.com/products/index.php [...] ive%20Labs

And lastly, that's about $1500.

I do know there's a nice calculator on my computer, but I'm just to lazy. I don't care to much about overclockability, so that doesn't need to be a huge worry. I'll only be gaming on a 24 inch HD monitor for a good while, before I get myself some 42+ inch beast. I didn't quite check to make sure everything is compatable with eachother, but I'm sure they are. If you can think of something I should change to make one set up better or something, please feel free to shout out. As I said, money isn't to big of an issue, but I'd like to keep it around the $1700 marker. $100-150 over wont kill me though, haha. Oh, and sorry if it looks horrible, I'm tired and need some sleep! Thanks for your help!

Incase you are wondering, I haven't decided on an actual computer case or power supply yet, but I think these will be all right, haha:
Computer Case = NZXT Nemesis Elite ATX Aluminum Case
http://ncix.com/products/?sku=2565 [...] cture=NZXT
Power Supply = Thermaltake Toughpower 1200W ATX12V 20/24PIN

Wow... for Build #1, it wasn't suppose to be that CPU, haha! Let me fix it up, thanks for pointing that out. as for the PSU, I figure go big, or go home , haha.

I know you said your not interrested in overclocking the but extra 300 bucks for the i7 950 vs the 920 is not worth it. I'm with gkay in recommending the 920, with a nice cooler.

I can also confirm your PSU is overkill too, can save yourself a few bucks. Another one to maybe add to the list of psu's to think about: Antec Signature 850 -> Best psu i've come across so far. Could also handle 2 gtx 295's.

Are you still in need of help? If so, read the sticky on how to post for build help and start a new thread, it will help get you more value out of your builds.
