Dear sirs

TBH the second one is more on my budget, but I cold even stretch for the first one.

I use my laptop for business purpouses (for which it is more than enough ... even my current Shark) and for light to moderate gaming.
My specific questions are:
1. I play mostly online FPS games like CS GO but other as well.
2. No need for playing at UHD settings. High or medium settings are OK for me.
3. I will be buying an external 144 Hz monitor in near future so this compatibility and conectivity is really important for me.
4. I cant really find a lot of pictures of internal cooling system for PA71 so please describe or provide a link. I found some pictures of fan disposition for N870 and it has two cooling fans (correct?)
5. Portability is also a concern since I do need to be mobile with my laptop from time to time, but everything even a bit bulkier from clevo et 370 is OK

To resume, seems that the main difference between two builds are
CPU... i7 7820HK vs i7 7700HQ
screen .... 17" 75hz IPS G-SYNC LCD 1080p vs 17" LCD IPS 60hz 1080p
internal laptop architecture ?? (cooling fans disposition)
external conectivity??
moterboard??

Is this upgrade worth the extra cca 300 EUR?

I have other questions regarding proforma invoice (VAT taxes) and shipping but maybe we can discuss that by mail.

Thank you in advance
