Ready for SB/Bulldozer Gaming system.

Okay, idea is, as its coming up to Christmas, is to shout myself a new rig  
However, as, SB and BD are coming out rather soon; I'd like shift money away from processor/motherboard; towards GPU and an SSD.

Resolution: Will be playing combination of everything, at 1920 x 1080


SLI: Whatever card I get now, I'll grab another one of later when I swap to the new architectures.


Parts not required: Keyboard/Mouse/Speakers/Monitor/OS. (any peripherals)

Current Ideas/Selected Parts:

Note: I'm Australian, so newegg/amazon not available   Am purchasing all my parts through local retailers.

CPU: Phenom x2 555 BE

Cheap, does what I need; seems good for experimenting with overclocking. Possibility of four cores. $95


Motherboard: ????? Am currently looking at the Asrock 890GX Extreme for $140, but I feel there could be a cheaper solution out there...Anybody?


RAM: Just a G-Skill 4GB Kit for $75, perfectly happy here.


GPU: Would like to spend between $150 - $ 300 here, and of course, SLI in future.

Am looking at:

GTX 460 1GB = $213
Radeon 6850 = $212
Radeon 6870 = $289
GTX470 = $295
2x GTS 450 = $259 (this choice would negate SLI in future, but awesome performance no?)


PSU = I'm really not sure how to pick one? :S Helpies?

Cooling: A Hyper 212+/ $31


Case: Coolermaster 922 HAF $135

In total..comes to around like...$800-$900 ish; and thats what I'm looking to spend. But any cheaper suggestions, or just ideas in general would be very welcome.


TLDR Version:

GTX 460, Radeon 6850/70, GTX 470, GTS 450 sli, which is best  

Motherboard: Budget AMD/Suggest  

PSU = HELPS.

Thanks guys
