Integrated Graphics Card Question

Hey,

I've been searching all over the net at different stores, looking for a good laptop for my brother. I have been initially eliminating anything with an intel graphics card, as I've heard they aren't that great. But it's making my search very hard, as pretty much everything in my price range. (Max $700 CDN plus Tax) seems to have an intel graphics card, or sometimes another basic integrated graphics card.

Anyway, I'm starting wonder if the Intel GMA 4500MHD is good enough for what he wants to do.

He won't be playing high-end gaming. He wants to play the old Roller Coaster Tycoon 2, and flash games. As well as watch dvds and movies on his computer. That I assume the intel gma is good enough for. Please correct me if I'm wrong.

But what he does want to do sometimes is some video editing. He will probablu use Movie Magix, and its just standard digital, nothing hd.

The two computers I'm looking at now have.
Intel Core 2 Duo T6600 2.2GHz
4 GB DDR2 Ram
Intel GMA 4500MHD
Windows 7 Home

Now, even though they have the intel graphics, will they be able to do some video editing?
I'm assuming they will, as I only have a AMD Athlon Dual Core 1.9ghz, 3gigs or ram, vista, and a nvidia 8200m. It can get kind of slow on my end, but its still good enough. I assume the one above would be better, but I wanted to check since I seem to read many things against intels graphics.

Thanks.
