Msi gx660/ Radeon HD 5870 help?

So today, I was playing a few games like Black light: Retribution and League of Legends and I noticed that there were this spikes coming out of the some of the models in the game. They seemed to stretch off the screen on BL:R but would go to a point on LoL. Exactly what is it that is happening as tried updating the drivers but that didn't change it at all so I'm a bit confused on what I can do to solve this problem. Do I have to replace the GPU? If I do then how much would it cost?

They are together, as far as I know this has happened only today. They did have a change in their graphics engine which was a few days ago but these "spikes" never showed up until today. I don't get artifacts ,for now at least, but just these weird "spikes" in which 3d models have one part of the model sticking out.
