So when looking at gpu specs, what should I look for and what should I stay away from?
It's going to get really technical again
Ideally, this nVidia product
matrix would have all the info you'd need to make that decision. I'd say make sure there is a YES in the first H.264 column (at a minimum) and (ideally, also) in the first H.265 column and you'll be in good shape.
Unfortunately, the laptop/mobile versions (which end in M or MX) are not even listed there. Looking at nVidia's mobile GPU
page lists all of their models, but even digging deeply into the spec pages will only list whether that chip has an H.264
DEcoder, and has
no info at all on whether it can
ENcode H.264 or decode/encode H.265.
The best list I could find after
lots of searching was this
page, where #3 near the bottom of the page lists all of the nVidia laptop GPUs that support the 2 main video encoders. Make sure you get a laptop with one of these if you want to use it for editing and producing video.
Believe it or not, some people swear they would
never edit video without a powerful GPU, and some people don't even bother and rely solely on the CPU (or with an i7, the built-in iGPU) - so there's a wwwwiiiiidddddeeee range of opinions here.
About the only thing I can say is that it's always going to cost more to have a discrete GPU, and almost all of the mobile chips are there for gamers, with us video editors mostly an afterthought unless we're willing to pay for the most powerful mobile chips. For anyone on a budget, I refer back to my earlier post where I believe that getting a new i7 is the most important thing. I will now also make 8GB my min recommended RAM.
Other people may have different opinions, but we're all trying to give you enough info to make an informed decision.
