I am hoping to play 4k videos smoothly, and edit fhd videos using premiere pro, vmware Other than that ,mostly serving internet , microsoft office These are my concerns. i5 8gb ram is the most popular version and price performance ratio value. I heard issue with loud fan noise ? Unsure if this is able to play 4k video smoothly? edit fhd video using premiere pro? i7 16gb ram seems to power limit thottering making it same performance as i5 and battery life lesser than i5 8gb There's only 2 year warranty with microsoft complete, Is it sufficient? compared to normal laptop of 3 year warranty. and is now the right time to get 1 since it have been launch 6 months ago, or should i wait for pro 5 which is rumor june/july or october? Thank you.
