Thinking on building a mining rig with 6 5970s grabbed from ebay here and there.
My investment in to this rig would be around 3.5k +/- 300$
I would get this system if i order now in 3 weeks or so, considering i'm not in states anymore, moved back to home country (Ukraine)

Electricity is 0.9grn (grivna) KW/h or 0.109c (USD) KW/h

Is it too late with GPU mining while ASICs are coming out next 2-3 months?
Or should i go with BFL preorder...

Thanks!
