The i7 CPU at your link is not compatible but an i7 3517U would be, see here
For such a minimal gain in processor speed I suggest that you reconsider the upgrade and due to the following reasons;
The i7 CPU is very expensive.
The BIOS will need flashing to accept the i7 CPU, your MB is hosed if this goes wrong.
The i7 CPU could arrive DOA and leave you financially out of pocket and/or in a drawn out dispute fighting for a replacement or refund.
The present i5 CPU and the only i7 upgrade available to you are almost identical in every way except the minimal gain in CPU MHz and the i7s 19 Clock Multiplier;
i5-3317U specs here and your only i7 upgrade option here interesting that both CPUs were released at the same time but the i7 cost more than $100 more
If you do decide to proceed with the upgrade let us know and we can look for the right i7 CPU for you but closer to home, no disrespect intended but there are too many poor products come out of China and Hong Kong which is a shame for the reputable sources.
