I got enough litecoin to dump on a 7950 this will jump my hash rate from 871khash/s to 1471-1521khash/s, or should I hold my ltc?
Seriously.
What do you guys think? Hold or dump?
I think LTC mining is going to be extremely profitable. I'd buy a card, but I'd go for the 7970.
Don't listen to this guy, 7950 all the way. I'll lay it out for you and show why serious miners do 7950.
7970 gets 750 according to crypto. Most people get less however.
7950 gets 650 though most get less.
Both can get the high numbers with much testing and work.
Based off of top end numbers:
7970 = $400 = 1.875 h/s/$
7950 = $290 = 2.24 h/s/$
per card, yes, but you get something like 3h/$ if you buy a 5830, would you be buying a 5830? no because there's only so many you can fit on a rig, before you have to buy another set of mobo/ram/cpu etc.. The card that give bigger hash per PCIE slot does have its advantages, especially if space is of concern.
6 7950 per computer vs 6 7970 per computer the 7950's still come out cheaper per k/s/$
And the endless debate begins....
There are simply way too many factors that one can consider. I'd just roll the dice and pick one.
It's only an endless debate if people want to go with unrealistic numbers and try to justify their buyer's remorse.
Gigabyte 7950s will get 600kh/s minimum. All of mine (12) get over 650kh/s. Most get just under 700kh/s. Mind you, this is with extremely basic overclocking - no fine tweaking whatsoever. Other brands of 7950s will easily hit 600kh/s with basic core overclocking.
Most people with 7970s can't even hit 600kh/s. 700kh/s+ is extremely rare. A friend has 3 of them and they are all poor performers compared to his 7950s, and nearly every post out there has the same results.
For the price of three 7970s, you can buy four 7950s - even if you get those 7970s on sale. Think about that. The math is extremely simple. Your six card 7970 rig is extremely shit value compared to the six card 7950 rig. This is before we even go into the extra costs of powering -and having the hardware to power- the 7970s that use more wattage compared to the 7950s. Even when overclocked the 7950s will use less wattage than the stock 7970s.
Debate over.
