Might as well hang onto the 680, IMO. It'll be better than the built in one but it looks like they're going for a couple hundred bucks on eBay if you're really looking to sell

I would hang onto your GTX 680 as it will outperform any on-board graphics. If you already have it why get rid of it? Anyway the performance from the Skylake on-board graphics are for Media usage only. Even if you are going to play the odd old game here and there, I doubt it will be able to keep up. 

I would say that you should definitely keep your gtx 680 because that is worth anything from £160 to £210 buying used so why get rid of it... However that it also a good reason to just sell that and buy a whole new PC with it from just your GPU lol. If you did go for skylake I would get an i3 6300 for general tasks but will still keep up with older games and some new if that is the case. 

You can use stuff like MKVMerge in the MKVToolnix kit - freeware. Load the file into the software, uncheck the subs and audio, remux the video. Or just extract the video by itself - not sure what you're using it for though...

I got a good LoL out of this one.
