Christian,
  am liking the new ccminer, definitely a boost from v0.1 with my 750ti's     you had mentioned 500mhs mining FC with 6x750ti not overclocked... was this actually achieved on a rig with risers?  i can't get close to 500 unless i overclock..  anyhow, big improvement nonetheless!  i just sent you 2ltc for your efforts.  great work!
