I'm looking for a laptop and plan some light gaming and running VMs from time to time so I looked into the Dell XPS line and they are starting to offer some nice rebate and I was wondering if I should wait for their 2018 line up. I kinda like the 2in1 factor but it's not a deal breaker. Performance wise I'm not sure if it's worth giving up on a significant rebate for the small increase in performance from the 8th gen processor. What's your take on it ?
