Either one will do fine for business. Overall the i5-2410 will be more powerful than the Phenom II N970.
For gaming neither is optimal. Both have integrated budget graphic cores, but the Intel HD 3000 in the i5 is more powerful than the Radeon HD 4250. The Intel HD 3000 is comparable to a desktop Radeon HD 5450.
Other than the lower price, the only good thing about the Acer is the larger screen and higher resolution which allows you to be more productive since you can see more on the screen. For example, on a 1600x900 resolution screen you will see more rows and columns in Excel than on a 1366x768 resolution screen. However, there are two downsides:
1. Larger screen means bigger laptop which means heavier laptop.
2. The higher resolution paired with a weaker video card means playing games at native resolution even with low graphic quality is not a good idea.
Personally I have a 17" ACER laptop, and while there's nothing wrong with the laptop specs (i5, good graphics, 4GB RAM, generous HDD space), the laptop itself is just awful. The keyboard has been problematic (missing letters when you type) and the mouse track pad is even worse the mouse jumps about and you really have to bash the pad for a mouse click, after a few attempts I find myself giving up and clicking the button.
If I attached a separate keyboard and mouse, then the laptop would be perfect, but that generally defeats the idea of portability and I just find that I always use my desktop instead.
I may have just been unlucky with the laptop I got, but its bad enough that I would never buy from ACER again.
