75' Cat6 vs 100' cat7?

I have a gift card for Newegg I want to use, and I need a longer (and faster) Ethernet cable.

75' Would be the perfect length, but Newegg only has the Cat6 cable in that length (http://www.newegg.com/Product/Product.aspx?Item=N82E16812119200).

However, they do have a nice 100' Cat7 cable (http://www.newegg.com/Product/Product.aspx?Item=N82E16812119318). However the extra 25' is not going to be needed.

The Cat7 cable seems much nicer quality and I'm sure is generally a better choice, however does having a coil of 25 feet of extra cable sitting there cause any problems? I know the cable is shielded should help with something like that, but this stuff isn't my thing so I really have no idea :)

So, would the extra length + having a coil of cable cause the performance to be somehow less than the correct length Cat6?

Appreciate the advice!

The difference between cat6 and cat7 is that cat7 was developed to have reduced crosswalk and other interference. If's not needed unless you plan on running it near possible sources of interference.

The cable with the extra 25 ft won't be noticeably slower, so don't worry about length until the cable starts to approach the maximum allowed.

I would go with 75ft one. It's much cheaper and will give the same performance as the other cable. I would expect that they both be of equal quality as they are both made by the same manufacturer.

All cat5/cat5e can do Gigabit speeds if have a Gigabit router/switch.

Megabit uses 4 wires of the Cat cable where Gigabit uses all 8 wires.

For length, all are capable of up to 100meters. 5e has better shielding so less interference and would perform better than standard 5. Cat6 is also shielded and has thinker gauge wiring so would be more ideal for longer runs. Don't bother with Cat7, either 5e or 6 will be more than enough.

Keep in mind Gigabit speeds is roughly 112MB/sec, so from this point forward will depend on your HDD/SSD setup.
