Have a bunch of varied GPUs pointed to middlecoin for several months now, and wanted to extend a thankyou to H2o for fixing EU server again, having quite high ping to the US one from Sweden

My question is regarding cgminer - should i bother testing other versions than the ones i currently use (3.1.0 and 3.3.1), if it somehow benefits multipool mining?
try to use 3.1.0 for my older cards (5870 etc) and 3.3.1 for R9's etc..
