with 4 7950 and voltage tweaking,
I get ~ 2400 Kh/s / ~640 Watt at the wall.

How much wattage do you think 2 7970's would pull?

any psu over 600watt should be fine as long as it has at least 45 amps on a single 12v rail.

I'm currently mining YACoin (a Scrypt-jane coin, so it's a bit different than normal Scrypt coins like Litecoin):

GPU:	Hashrate:	Power consumption:	Cheapest Price:
7790	57 kHash/s	50 Watt	€ 102
7950	94 kHash/s	200 Watt	€ 226

The 7790 has more than 60% of the hashrate of the 7950 at only 25% power consumption and costs 45% of a 7950. So I's say the 7790 is the smarter choice, you just need more cards Wink

I will check with Litecoin in a minute.

Good points

MSI Z77A-GD65 is what I have. You can run 7 gpus on them. They are very popular on the forums as well.

EDIT: I should add you need to use an Ivy Bridge Processor for the last PCI slot to be active.

General consensus is that the 7950 is the best bang for the buck.

I believe the 7750/7790 aren't too great for scrypts.

Sorry, I have edited my OP, I meant 7950 and 7970 and above.

Thinking of getting a motherboard with maximum gpu slots for litecoining. Assuming I am running a state of the art gpu 7950/7970 or above, can anyone advise on motherboards I should look at?
