Yah within 1-200 mhz and it can remain competitive. Clock limits arent a bad idea, but they need to be set high enough for world records to get broken in competition. There should be no limits with regards to any other hw because its not necessary. There is so much involved with clocking some gpus very high, that it almost never comes down to a matter of binning cards with really high LN2 level overclocks. Maybe if you run your gpus on air unmodded

I am considering sponsoring a worthy/needy team with a full setup of cooling for TWO guys. It would be funny to be competing against a team with my company name on it
