Hey.
I'm thinking about a little mining project.
I thought of running around 2 comps at first, and upgrading from there on.
Setup:
2x 5870 / 5850 since they generate a lot of MH/s and are really cheap.
Gigabyte GA-PH67-UD3, Socket-1155 (Cheapest SB board that supports CF)
Intel Core™ i3 Dual Core i3-2100T
Cooler Master GX 550W PSU
Random cheapest case and random cheapest memory.
- Will this give profit in the end? They will run 24/7.
firstly, if you're going to run AMD GPUs, you should consider AMD CPU and chipsets, rather than mixing AMD and Intel. i hear they don't like each other. think about it.
secondly, if this is a dedicated miner a single-core CPU is fine: like a Sempron 140. 45 Watts. the CPU is irrelevant to mining.
thirdly, i agree generally that a 550W PSU is too low. keep in mind that you may want to upgrade your GPUs someday.
lastly, don't forget the random fans...
