These risers are fine? And some watt consumption question, and cpu :P

Just right away to mention, I will never run more than 3 cards, I will never run a dual chip card.

1x to 16x = >http://www.ebay.co.uk/itm/PCI-Express-PCI-E-1X-16X-Riser-Card-Extender-Ribbon-Cable-1U-2U-chassis-/181111923501?pt=UK_Computing_CablesConnectors_RL&hash=item2a2b1ca32d

Is it fine to get these? Also, whats the cheapest CPU/MOBO I can get, that can run 2x 7950?

I'd use these riders also to seperate my cards so they dont heat so much.

Also forgot to mention, I'm a litecoin miner.

So the risers will be fine, however on the PSU can a 620w seasonic do 2x 7950?
