Processor Bandwidth necessary for HDTV

I own a Pioneer Elite Pro-800 using component video output from a Scientific Atlanta 3100HD for my 1080i source.
My question is how wide does the component video input freq.resp. on a pre/pro have to be so I won't notice a difference between running direct to the monitor or through the pre/pro? I love the picture and do not want to loose picture quality.
I'm thinking about purchasing an Outlaw 950 pre/pro but noticed it's only rated out to 45MHZ with others showing 75MHZ - 100MHZ.Is this bandwidth necessary??? Will 45MHZ be enough??? Should I look elsewhere?
I would recommend that you post this question in the HDTV Hardware section of the AVSFORUM.COM
No 45mhz isn't nearly enough. I have 100hz and I can still see a sligth degradation of the picture when my switcher is in the circuit. You can buy a separate switcher from someone like Extron that will handle the job.
