Well, let's suppose you were going for a red and black theme color wise. Here are some great parts for your build.

The parts your definitly getting or have
Power supply and case- $250

cpu- I7 990x $1,099.98

here's the parts you haven;t yet chosen

Motherboard- EVGA X58 Classified 3 EATX LGA1366 $400.88
http://ncix.com/products/?sku=55797&vpn=141-GT-E770-A1&manufacture=eVGA

RAM- Corsair Dominator GT 12GB 3x4gb $300
http://ncix.com/products/?sku=52470&vpn=CMT12GX3M6A1866C9&manufacture=Corsair

I still think you have to get two Nvidia graphics cards to do their equivalent of eyefinity(i'm not certain) so you could go with a HD6990, unless you'd prefer the GTX590
Graphics card- HD 6990 $749.99
http://ncix.com/products/?sku=59513&vpn=HD699AENF9&manufacture=XFX

Since you're getting an i7 990x, you're going to need something good to cool it.
Either of these would be good for the job since you don;t want a custom watercooling system.
CPU Cooler- Corsair H70 $99.99
http://ncix.com/products/?sku=54728&vpn=CWCH70&manufacture=Corsair
or
Noctua NH-D14 $89.99
http://ncix.com/products/?sku=47090&vpn=NH-D14&manufacture=Noctua

Hard drives- Caviar Black 1Tb HDD SATA 3 6.0gb/s $93.98
http://ncix.com/products/?sku=50895&vpn=WD1002FAEX&manufacture=Western%20Digital%20WD

or an SSD of your choosing

All together this comes out to about $2997.94 CAD

thanks for giving me an idea :)

if you can wait till summer you might be able to buy intels next gen Enthusiast system powerd by SB (core i7 dunno rest) 8 core 16T or an AMD buldozer FX(maybe the fx power times are back) cpu. it will defenetly be better than the i7 990X. and if you have time to wait than wait thil the die shrink for the gpus to 28 nm because it will increase the performance/ watt significant and will make it faster. it might have pcie 3 suport.

wow 3000 dollar rig ^_^ rich guy here!!!!i wish i have that much money lol

Not to be a nit-picker, but shouldn't this be in Hardware?

I think that you should spend more on the motherboard...use the gigabyte G1.Assasin it's the best for use a 990x.... Then choose Amd 6990... I don't know how much it will be but the MoBo is the most important component...;) good luck

Moved to Hardware.
