I just want to say HI and want to ask for some help with building my mining Rig Smiley

My Setup for beginning:

ASRock MB-970EX4 w/ cheap AMD CPU
A bit of Ram like 4 or 8Gigabyte
2x or 3x ATI 7770 or something else.


Could someone say me if this would be profitable?


Cheers!
With the 7770s you would get around 250 Mh/s: https://en.bitcoin.it/wiki/Mining_hardware_comparison
I would recommend a couple of ATI 7950s: http://www.amazon.com/Gigabyte-Mini-Displayport-PCI-Express-Graphic-GV-R795WF3-3GD/dp/B007581QHG
Why do you recommend 7950's over 7770's?  Is it to make more efficient use of the PCIe slots?  The 7770 is better at Mh/s / $ and MH/s /W than the 7950 by the numbers.

Oh, and that's one heck of an overclock to get 250 average out of a 7770.  Stock is around 200. (at least that is what I get out of mine with poclbm kernel.  I got 150 with phatk).

And, depending on what you pay for electricity, you will be lucky to pay for electricity much less get your investment back.
