First rig arrives today. Looking for feedback.

[minedeep]

Just got the confirmation.  This is what I have arriving in the mail today:

1 x AMD FX 4100 4-Core Processor, 3.6 4 Socket AM3+ 
2 x Gigabyte GV-R677D5-1GD Radeon HD 6770 Video Card
1 x Gigabyte GA-970A-DS3 AM3+ AMD 970
1 x Corsair Vengeance Blue 8 GB (2X4 GB) PC3-12800 1600mHz DDR3
1 x KENTEK 700 Watt 700W 120mm Fan ATX Power Supply 12V 2.3 EPS12V 2.92
1 x GAMMA Classic Series ATX Mid Tower Interior Steel Chassis

and its all gonna boot off of...

1 x ADATA Superior Series S102 Pro 16GB USB 3.0 Flash Drive
(Rolling my own live distro for this project based on Ubuntu 12.10.  I call it BitBuntu.  I'll release it on the forums when it gets smoothed over a bit.)


I went the conservative route.  6770's aren't going to win any bit-speed records but they will do something alot of your cards won't: Run COOL!  I paid $100 each new and under warranty.  I've seen people posting numbers ranging from 200-249Mhash/s per card.  I went with Gigabyte motherboard and cards because I've had good experiences with them.  As a system builder for the last 15 years, they've never let me down. 

Don't know much about the ram other than it was cheap. Also went cheap on the PSU but 700W for $40 (and new at that, check amazon) is a good buy. 

Now I know some of the elders are thinking, "you could have saved money on the CPU and RAM and bought a better PSU, newbie".  Thats not the plan.  My goal is to build a versatile mining rig that can mine other currencies as well if the market calls for it.  At first chance I'll be adding a better PSU, two more Gigabyte 6770s and another 8GB of RAM.  Some of the other cryptocurrencies are heavy on RAM and CPU usage (I believe litecoin is one of them). 

Oh and I got all of that for $500, overnight. 

Your thoughts?

Do you have a guesstimate of what your hashrate is goanna be around?

Single 6770 card produces ~220MH/s so about ~0.022btc per day per card. That's my guess. :p

Anywhere from 450-500Mhash/s with RPCminer and some modifications to the memory powering on the cards.  Plan on under-powering the cards memory and clocking the GPUs a bit.  Word on the street is they run way cooler than other cards even with clock modifications.

I've heard of 400Mhash/s without tweaking while running two of these cards side by side.

My bad, they were running Phoenix 1.50 on the setup they had.  And it went a little something like this:
