Been reading trollbox on poloniex and it seems the hot coins are X11 algo.
Mining X11 myself and I gotta say there's no question, its the future for GPU mining.
Here is a comparison of X11 to N-Scrypt on my rig (3x r9290) at fastest stable setup for each.
N-Scrypt - 1070-1090 Watt consumption, 90-92 deg C, Fan duty cycle 75-90%
X11 - 605-609 Watt consumption, 72-74 deg C, Fan duty cycle 45-50%
X11 is made for GPU! ASIC resistant, GPU friendly. Above stats prove it. Rig sits in my room purring quietly, hardly even notice it. Can't say that for Scrypt or N-Scrypt.
Of all the coins on X11 GPUc belongs on X11 simply because of the idea behind the coin!
I`ve read that there are no optimized miners for X11, thats why it is running cool and under low power.. GPU is not utilized 100%.. allegedly there are "private" miners that can achieve 100% GPU utilization with X11 algo..
