There is 5830's in my store should i buy one then buy another one when i make some BTC?
PS: 5830 is for $254 and the 6950 is for $375.
I'd say buy in, but start small. You say you have a gaming rig, then why do you need an 890fx board? If you want to use it as a pure miner, buy a VERY cheap mobo with 2 pcie slots or even 1 x16 and 1 x1. get a sempron 140, you dont need a dual core. And unless you care about your power consumption, don't get a 5770, get a 5830 or even 6950 (in the US 58xx seem to be rare I hear). You could also consider getting a second hand 775 board with a pentium, or 939/AM2 board. Worst case, you will lose much less than with your setup.
I wanna leave my current PC -intel/dualcore- intact, for gaming and work
And get a mining PC cuz i will leave it running and have no problem it eating my current PC resources.
And the 890fx board is very cool with 4 slots for GPU's.
Do you have any suggestions for the board?
My fav. store has only those:
GIGABYTE GA-890FXA-UD5 - AMD 890FX
GIGABYTE 880GA-UD3H . REV3.1
GIGABYTE GA-880GM-UD2H - AMD 880G
GIGABYTE GA-MA74GMT-S2 AMD 740
ASUS M4A88T-M/USB3 - AMD 880G
Otherwise, you could build a gaming rig with good mining GPUs, mine for a bit and then sell it to a gamer for good cash and little loss...
Yeah if i am done with mining (which won't be soon) i will sell it with a small loss or keep it.
