[Scgeeks] Can a celeron processor do what I want?

[Miss Betsy]

The application is a streaming video program.  I got a quote on a celeron 
processor.  However, a bright, young college geek says that it will slow 
everything down after a while.  There will also be a QuickBooks Pro program 
on the same computer which I know takes a lot of resources also.

I read that the celeron is like a compact compared to a luxury sedan.  Young 
college kid may just be always looking for the best, but I don't know enough 
about the applications to know if they need a better processor.

Another major factor to me is that even if the kid can find a whole package 
cheaper than my quote, the quote came with set up and training in the 
streaming video application.  The quote was for about $1200 (I don't have 
any of the figures with me) for new computer including webcam.  Is that 
ridiculous?  (there is more to this story than I am telling).  How much more 
could I expect to pay for the Intel Pentium?  I know there are different 
levels, but what I want to know is if I could make a case that the original 
quote is reasonable and would work, or how much more a more solid Pentium 
would cost if that's an issue?

These are the original system specs that resulted in the quote on the 
celeron
Pentium II 450 MHz or higher processor, Windows 98, Me, 2000 or XP (home or 
professional), 96 MB of RAM, 128 MB for Windows 2000/XP. (128 MB 
recommended).
