I went with a lenovo W550s a couple years ago,which is now probably not available from Lenovo but you can still get it from others sites. .I had windows 10 downgraded to windows 8.1 pro due to there was still many issues with certain drivers not working at the time for cutters,software and programs running on windows 10. I had 16gb ram installed( upgradeable to 32gb) with a 1 tb SSD and a good graphics card.Its also has 2 batteries built in to give longer use( 7 up to 17 hours) depending on what you do since i take mine out in the field to see customers etc. It did cost a bit around $2500 .But i know it will do what i need and more. I run my Scalps5pro,Vm software, Ai cc,Photoshop,Lightroom for my photography side and also Sony Vegas pro. It has never let me down. And it comes with a very awesome warranty which is like 4 or 5 years Full warranty.
