Hi there,
I am just about to start mining.
Originially I wanted to go into Litecoin, but due to the profitability charts on coinwarz.com I decided to start with different alt-coins.
I am going to streamline my mining strategies with a self-written script.

Hardware spec:
Board:     ASRock 970 Extreme4
CPU:         AMD Sempron 145
RAM:        4GB G.SKILL DDR3 SDRAM (2 x 2GB)
Power:      Corsair AX1200i
HDD:        Toshiba MQ01ABD032 320GB
GPU:        3 x Sapphire VaporX R9 280x

All parts are here on my desk, I will start assembling asap.

Any recommendations regarding a good performing multi alt-coin pool?
I already tried miningpool.co with a low-end setup but it seems to have payout problems from time to time.
