Should I buy a laptop made in 2012?

On trademe (NZ ebay) there are cheap computers from 2012 with 8 gigs of Ram so I can play Star Citizen and Blender. Or should I spend more and get a more current computer?

I can check on internet but I didn't find the right solution.
Any shared experience on a similar matter or additional things I could do would be appreciated.
