X202 Vivobook CT085H vs CT090H

Not sure if it's called the same worldwide, but where I live in Europe there's two models available on the Asus touchscreen x202:

CT085H

and

CT090H

the difference between these two models as far as I can tell is that the CT090H is:

$77 cheaper.
has Intel Pentium 987 1,5 GHz rather than Intel Core i3 3217U, 1,8 GHz.

Now my questions:

Is there any other difference between these two models?

And is it worth the extra 77 dollars for the faster i3 processor? I'm talking real world noticable difference here as in overall speed, difference in browsing, watchin youtube or hd-movies, gaming or anything like that or if there would be some other difference that it would use less battery or something like that?

I may be cheap, but I rather spend the extra money on a external bigger harddrive or something like that UNLESS of course there IS a real life difference that would benefit me.

Thanks for any help here as Im trying to figure out which one of the two to buy!

 

There is definitely a marginal difference between the two processors. I have a desktop running on a Pentium D @ 3.4GHz at home, and the i3 Acer here at work boots up drastically faster than it (and it runs noticeably smoother as well). While the i3 is considered a [modern] entry level CPU, it will outperform any Pentium you put it up against.

I say it's worth the cost.
