Well the 5570 isn't shown on the mining comparison list yet
https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparisonBut looking at the chart I'd take a guess and say you'd get about 100kh/s. (probably lower)
I've just had a look on ebay.co.uk and there are used 5570's for £40 delivered.
You'd have to get 3/4 of the them to match a 6950 and that will have set you back £120 at least...already.
I guess buying many lower powered cards would give you more redundancy, but my choice is still the 6950.
True, I think i'll just go for the 6950
Also look in the mining and marketplace forums on here as a number of people are selling off their old mining rigs so you can pick up all u need with the knowledge that the cards work and can get good estimates on hash rates for each card
Could try that, but my only worry is that if the cards fail, it'll be kinda difficult to get them fixed, I think ?
you can calculate by the number of shaders in the card as long as the card uses gddr5
see thread in my sig
Sweet thanks ! Looking now
