I have been away from the bitcoin scene for a while and am trying to get back up to speed.   I have 2 5830s sitting unused in boxes, and one in my main CPU.  I was thinking of what would be the minimal cost to put the 3 5830s in another rig and then buy a Diamond AMD Radeon HD 7970 for my main editing rig since it's around $400 now.

That should produce somewhere around 1.5 to 1.7 ghash correct if tweaked right?  What is that in bitcoins per day / week at the current difficulty and what pools / mining tools are now recommended?

I was using trix to overclock and then mining with aoclbf bitcoin miner before on Elgius.  That was over 6 months ago.
