I'll probably build a PC after this laptop gets out of date and is unable to accomplish all I want it to. I helped my brother build one, and it wasn't as hard or as time consuming as I thought it would be, although finding the time to make one would still be an issue.
RAM has never been an issue for me, I have 8 gbs and i've never even used 3/4 of it. Probably because I don't use video editing programs or RAM intensive stuff though.
