What do you plan to use the laptop for? You said you were using a student discount, so is this for college? Do you plan to use it for gaming, as a media laptop, or just as a workstation?
As a general rule, unless you're doing highly intensive operations like gaming or 3D modeling, a processor's speed isn't going to be the main bottleneck. We've gotten to the point now where the most important part of a processor's usability is its heat efficiency. What that means, essentially, is that newer is better. This is a Haswell i3, so it will be nicely heat efficient. Again, whether or not the processor is going to be good depends on your intended use.
