i'm looking for a single graphics card that can do about 900+kh/s with at least 2 or 3 cooling fans.. anyone know?
7990 if you are able to find one with decent price...but it is highly unlikely
Next would be R9 290 or R9 290x depending on the price you are able to find (should be good for 850khs), when I chose my cards
I just calculated the average from
https://litecoin.info/Mining_hardware_comparison to make an idea about obtainable kh/s and in reality
Igot +/- 5% (personal experience)
