On a 500$ budget thats easy
semperon cpu 35 (Best mining cpu)
pos case 25 (buy any atx case)
hd 7850 200 (GPU)
PSU 7150 (750 watt)
hard drive (sata) 25 (any mem works)
ram 50 (4 gigs)
mobo 75 (am3+ slot)
MIND YOU YOU WOULD NEED TO USE LINUX
AND IT would need to be wired in, not wirless
also if you would want to expand you would need a new gpu
OR buy a rig from me. Ill build one custom tailored for you with al mining software loaded up and ready.
We can work out price pm me.
I've just been doing a bit of research on GPUs and came to the same conclusion, that the 7850 gives the best bang for the buck, when you include power draw. What makes the Sempron the best CPU? Just because it's got a low power draw?
because they are cheap and widely available.
makes sense. the other question this thread made me think about is amount of RAM; is there a suggested minimum to mine with, and does that increase with multiple GPUs on one system?
Gpu's have there own memory
But as far as a budget rig is suggest that card. When building a full scale rigs i prefer 290's as the hash per card. think of it this way.
Budget rig (7850) Built rig (290)
BASE 300$ 660$ Base Built
1 card +200$ +500$ HASH .8/$ .689/$
2 cards +400$ (need new psu) +500$ HASH .88/$ 1.03/$
3cards +200 +500$ HASH 1.09/$ 1.11/$
So in the end your hash per $ is better with a built rig on 290's
with 7990's i think on 2 cards your hash/$ is assuming on the built base is 1.15/$ but the cost is 1k per card
