My kids are complaining about lag on their laptops when they play minecraft. The machines are a three to four years old, bloated with old stuff, and I'm thinking it might be easier to buy new laptops than try to really reinstall the old ones.
But I don't really want to spend too much money on the machines. So I guess here are my questions:
1) Is windows 7 or 8 less resource intensive?
2) What is the lowest recommended ram for a solid machines that will last them a few years?
3) Does the laptop videocard really matter for minecraft lag?
4) What processors with the above OS and RAM will equate to a solid quick response laptop.
