>>>what benefit will 3DNow provide for the K7, considering that the K7 will have three separate FPU execution units?<<< good question
1. one of the K7's FPU execution units is load/store only
2. the peak mflops rate for 3DNOW single precision will still be double the raw FPU max, which presumably is 2 flops/cycle.
3. the single precision 3DNow instructions have lower latency than the FPU, allowing much faster operation for recursive computations
