I7-2600K, GTX570 SLI. Does this look like a decent setup?

Intel® LGA1155 Core™ i7-2600K
Corsair XMS3 1600MHz 16GB Vengeance™ CL9
Corsair SSD Force Series™ 3, 120GB
Gainward GeForce GTX570 1280MB PCI-E
Gainward GeForce GTX570 1280MB PCI-E
Gigabyte GA-Z68X-UD4, Socket-1155
Sony DVD±RW AD-5280S-0B BLACK/SATA
Corsair Powersupply TX V2 850W
Cooler Master HAF 922 Midi

I am curious about the case and motherboard.. will i be able to install 2 GTX570 cards on them? and get optimal performance? And is the PSU strong enough to run it all?

If you plan on overclocking, bump the PSU to 1k.
