Upgrade to intel 990X now? or wait till Sandy bridge-E?

[crazygamer444]

Hey guys,
I need some help on my new build specs are as follows:

3x MSI gtx 580 lightning XE edition

asus xonar xense 7.1 sound card

corsair AX1200 psu

Intel 990X

asus rampage iii black edition

corsair dominator gt 12GB @2000

I know that the 2600K would be the better buy, but I haven't seen one LGA 1155 motherboard that will support 3 gpus (I'll be running 3d vision surround) and 1 sound card without water cooling the gpus. So my question is which should I get? The 990X (which I know is some what out dated now but I'm cool with it) or wait for sandy bridge E? Either way I'm waiting till bulldozer comes out, but as of right now which of the 2 should i go for/wait for?

Thanks!

P.S. Will the corsair ax1200 psu be enough to power all that?

If its coming out within two months I would wait for it.
