Hi everyone,
First post here. I've just ordered an iMac 2.8 as well, with specs matching the 3.06 (8800gs, 500gb). Just wanted to make sure I'm not missing anything significant by eschewing the extra ~260Mhz for ~$150. IIRC, the only difference in the processors is the multiplier setting, and benchmarks of the two systems with the same video card/hardware show just fractional difference.
For those more knowledgeable, does this sum it up? I just want to make sure there's nothing concrete (stuttering on HD video, etc.) that I'm giving up with the 2.8 that wouldn't be a problem with the 3.06.
