It will not be a significant difference, there are only a few times I've heard a cable difference that could be considered significant such as Tralucents silver/gold and silver cables which run at a price more than IE80 itself , even then some would question my opinion and blame my placebo effect due to it's cost. Cables are a touchy subject on head-fi why you get some unhelpful people. The cable in your link is just a basic upgrade and one thing to remember with cables is they're really only for tweaking, so while changes can be heard it's often not the big explosion people are expecting and rather subtle.
Sunrickys cables are decent though I know of some that offer a better price to performance ratio, you would need to spend about $50 USD. Just remember that a cable upgrade should always come last for fine tuning your rig, and can be rather bothersome to get right as I have recently experienced with my 1Plus2 unit.
Here is the cable I was speaking about:: (he has none in stock)
Also consider Dark Lord another silver plated cable made by Sunricky. very popular a while ago for TF10 users.
