Doesn't that mean they have newer models then? I don't really understand the crave for 5830s if they have newer ones that would be better...?
If you could explain this concept to me I'd be very grateful. Thanks!
Yes, there are better models out now.. however they have been tweaked more for their primary purpose: gaming, reducing their mining output. The only reason the 5000 series are good for mining is because of the low price (old models) and the high number of shader ALU's which perform the math required for bitmining to work.
