It's only happens to Tropico 4, Hero might and magic VI, Cities XL 2011. I can play Starcraft II, Shogun II, Fallout: New Vegas ect ... just fine (at low graphics setting of course ).
I ran a test from www.systemrequirementslab.com to see if my system pass the requirement for Tropico 4, and it's even pass the recommendation system requirement.
I did try Vsyn as some suggest (from others thread), Vsyn does "stop" the tearing jumping around, however it doesn't solve the problem (as you can see in the pic).
Based on your images those are heavy artifacts not stuttering or tearing. First try updating your drivers. If it only happens in some games then it may just be drivers. It also happens if your GPU overheats or has gone bad so check those temps.
