well i got this laptop from crigslist for 350 so far i have no issues. and im not worried about the time to take it about and so on. I was going to do it when i get home and since i was going to take it apart i mid as well replace the TIM on the GPU. I think it may do it some good but so far since i replaced the drivers it seems to run fine. a little hot but that expected from a gaming laptop.
