Well I have few years of linux experience, but I find this system still so new to me when it comes to modifying system files (or something similar). Got 17.3 Mint here and oibaf ppa for mesa. I used this for r9 290 radeon, but I am upgrading that card. Meanwhile I noticed that I can really play dota 2 with intel. And the same ppa works for intel too. I haven't noticed any tearing issues with intel, which I had sometimes with ati. 

Is there any guide which I could go through to check if I have all the files installed and setup that I should?
