not even close!
that will cost you... what? 30.000-$40.000???
it will make like 45Mh and with that you can mine 400LTC/month, well not even that since difficulty is rising every 3 days for LTC... even if you don't pay electricity you will still need like 7-8 months to ROI.
so you wan't even return half of what you invest you will be run over by scrypt asic and they are around corner.

stay away from gpu-s IMHO.

pay attention on this:
