Thank you for the suggestions.
I don't really have any preconceived brand preferences, so as long as it's a company I've heard of, and it works well, it should work for me.
USD. Sorry, I usually specify this.
Usually I would also recommend the 5000 series for under $1000 but the 7000 series is having a sale where some similarly speced models to the 5000 series are cheaper.
My only concern with these would be they seem to only have SSDs (EDIT: At least according to Dell's website. Best Buy claims it has a dual-drive system). I'm also going to using it for work, so a large 1TB HDD would be highly beneficial, even if it were naturally slower than an SSD.
Thank you for all your help!
