Nope CF(compact fluorescent) isn't powerful enough for SPS. I had the config you described, 8x 64w, and it couldn't keep montipora alive 4" from the surface. The issue is that they don't penetrate and there's alot of lost light. If you want to do SPS, your options are basically T5 with good reflectors, metal halides, or LEDs which is what I'm using now. I have a 100 gal, running 60w of Cree LEDs on half the tank and I'm keeping montipora, stylo, and acro. They've colored up noticeably since I bought them. They were under metal halides at the store.
