And now I just realized that my 3x290 + 1x290X rig (used to be one more 290X but that one recently burned out

) takes out 1/15 of the whole network speed.

I guess I could easily mine it directly without the help of a pool (may be I actually will, just because that feels better for me for some reason I can't shape into words). And now I miss my 5. card even more.
So your 4 card rig is getting 1000 Mhash mining DRK? Interesting claim...
