Which is better for a high end rig?

So basically I'm planning to upgrade. My friends all have high end rigs and I kid of so to but I'm still on 775. 1155

Intel core 2 quad extreme qx9770 @ 4.2ghz
8gb 1600mhz ram ozc 1866mhz
Xfx 790i ultra sli
3 way Gtx Gtx 470 OC
Everything mostly water cooled
Xfx 1250w PSU

Also have a workstation but keeping it as a work station.

So I can't choose between the

Evga x58 classified 4 way sli or the
z77 sabertooth

x58 only supports 24gb ram but it's all 4 fb and 8gb right now is expensive. The motherboard also has a great over clock ability and 4 way sli support. The mother board does not support USB 3.0, pcie 3.0, Sata 6gb/s, and Ivey bridge support. Planning to use a 920 and later a 980 next year or so. I'm getting the CPU (920) And mother board from my mate for the price of a new z77 they are rma replacements.

On the other hand

The z77 Sabertooth has a nice look with the thermal armour. The mother features support only for 2 pcie x8 lines 3.0 and x4 last line which is no use, USB 3.0, Ivey bridge support and Sata 6gb/s. The z77 doesn't support 4 way sli which I'm planning to use. It is also not stable for over clocking and chipset can't be water cooled. Atleast it's tax so I have more chooses for cases which I will explane later. Any ways the z77 does not get a high benchmark even with the best 1155 CPU.

Cases.

I can't choose between a corsair theme or random gear.

Wanting the buy the corsair 550d because it looks good and is very quite but doesn't have great support for water cooling or support for ex atx for the x 58

Also the corsair 600t looks so ugly.

Cooler master styker looks alright but just isn't corsair. Will have to by another psu if I got with the cm styker white cuz my psu is yellow and doesn't fit in well with the white and red theme. Sealing of themes it would go well with the x58 as it supports e atx too. The case is good for water cooling also but lacks the ability to be quit when I'm gaming.

Sorry on iPhone forgive me for gramma

Why not got for a 2011 socket
