Not really, for every day use.
There are i5 processors that will do better than i7, for general computing
purposes, particularly if you put the extra cash into some more memory.
Typically, if you use large spreadsheets or do some video editing or
intensive gaming, then you want an i7 because it allows a lot more
hyperthreading; i.e. if you get an eight-core I7 it will run 16
hyperthreads, while an I5 is limited to four threads, even if it has four
cores.
If money is not an object, go for the fastest I7 you can get with a good
amount of memory. But, if you are just using it for everyday things like
email and browsing, then go for a processor which might be a bit less
powerful but has a lot less energy usage so you can conserve your battery
for more operating hours.
