Help in speed variables iMac/Mac Pro

[Harlowgold1]

I am still holding back on my order...not sure if I want an iMac or Mac Pro. I have two monitors but I guess I am confused in hearing an iMac is faster.
Specs - iMac 3.06/4mg
or
Mac Pro 2.66/4mg

So which would be faster with my video and general work demands?

Thanks! Jenny

since im not too knowledgable about proscessors, i will have to say the mac pro because it has 4 cores and the imac uses mobile hardware but the imac might be faster for single threaded apps because of the higher clock speed but maybe someone with better knowledge than mine can fill you in, but hey im only 14
