I started with a 965 on the R2E on water and the sucker screamed for me. I was posting amazing speeds at what everyone was telling me was low voltages ?? Then I got a Classy (758 w/NF200) and put it on phase with the 965. Definately was a learning curve but once I learned it I fell in love. With the 965 all you have to do is throw volts at it and it says "great, let's go faster" lol Then I got a 975 and put it on the classy under phase... it went faster, and scored higher even at the same speeds, but throw volts at it and it says "hey, what the frack you think you're doing??? turn that stuff down"
Been using the R2E with a D0 920 as a gamer, but can't get warm and cozy with a locked proc, so I decided to sell the board and bought a new Hydro copper classy to use as the gamer. Not sure if I'll sell the 965 or the 920 at this point though
