Help me decide: e4500 vs. e6550

I'm buying a new computer to power our church's media presentations. I'm wondering which CPU to go with: The e4500 or the e6550. Will I notice a performance difference doing:

1. slideshows
2. Live video recording via firewire
3. playing DVDs

We might be doing two or three of these things at the same time using dual monitors/projectors. Obviously, being a non-profit, we try to pinch our pennies. In terms of a)performance and b)longevity, is the additional $50 worth it?

We will not be O/Cing this system, as our corporate discounts on OEM is too good for me to spend my time building it myself.

You would get away with an e2180 no probs... you could even Overclock it to get a bit more out of it.

I CANNOT OVERCLOCK! This is not a home build. It is a business class machine that I have to purchase on a corporate account. OEMs like Dell and HP do not allow overclocking. I have to decide if I'm going to get $50 of performance boost with the e6550 or if sticking with the e4500 is okay.

The cache + FSB will amount to something like a 10-15% increase in most applications. I don't think it'd be enough that you'd notice it too much... but it might be worth it for you, I don't know.

If it was just for business I would say the E4500, but as it is for a church you will need the most powerful CPU possible because it will be getting stressed by processing an incredible amount of bullshit. I might be wrong if the E4500 is using a bank of illogic processors though.

get the E4500, slideshows don't create alot of stress, and nothing else that you might use on a church computer that I can think of would require a E6550.

Get the E4500.

You won't be able to feel the difference.

I would go E4300, if that is an option. It will handle what your planning to do fine.

You really couldn't go wrong with either choice. So it really only comes down to the money. I'm sure the CPU will be very happy with the tasks your give it!
