I have a Corsair CX600 in my current build and was wondering what the best dual card setup it could handle with my current setup.

I know it can easily handle a single Radeon 7970 Ghz Edi or GTX 680 and probably nothing more. My question is more towards an SLI / Xfire setup. I'll be switching to an Asrock Z77 Extreme4 and an i5-2500K (getting them used from a friend) but everything else will remain the same.

Build will look like this:
CPU: i5-2500K w/ CM Hyper 212 Plus
Mobo: Asrock Z77 Extreme4
RAM: 2x4gb G.Skill 1333 CAS9
GPU: Radeon 6850 (looking to upgrade AFTER I get the new Mobo & CPU)
SSD: OCZ Agility 3 120gb
HHD: Seagate Barracuda 320gb SATA III
PCIE: Asus b/g/n Wireless Adapter
Optical: LG DVD RW
PSU: Corsair CX600
Case: Antec Gaming One w/3 120mm fans (non LED)

With that power draw what's the best dual video card I could run? It's single 12v rail is rated at 46A for 552W. From what I've read (seems like everyone's power consumption charts are different) it looks like I could maybe run dual 7850's but I think a 7970 / GTX 670 would be the easier & more efficient way to go.

2x GTX660(non ti) is the best multi card setup you can buy without changing the PSU.

There was an article on toms about 670 gtx from Asus ( I believe ) that used 1 8 pin connector but Im positive there would be a huge premium for them as they were shortened by a very noticeable amount using a custom PCB plus the lowered power requirements.

So they likely cost around the same as the 4gb versions on newegg up to $450 each.

For 195 or so each this will give you the best possible outcome with a dual card setup

Maybe look at a single 670 or 7970. These two cards would be less powerful than the 660's but also leaves you a future upgrade option in the future when the prices come way down. Remember that 2500K CPU will not be outdated for a long time.

My friend just upgraded to an i7-3770K, Asus Sabretooth and Corsair H100i so I jumped on the chance for his i5, Extreme4 and 212 Plus. I've been looking at the Gigabyte OC 7970 3gb (factory OC'ed to 1ghz core, might as well be a Ghz Edi) for $400 as a single card solution for now and then hopefully grab another (with a newer PSU obviously) in a year once AMD fully releases it's new line and prices come down.

However, the dual GTX 660's are very tempting (albeit $100 more now) for the performance increase.
