I recently bought a 1080ti and after about 2 weeks of owning it I began noticing random spikes in GPU usage, frametime and FPS during games and benchmarks http://i.imgur.com/nHrhIAr.jpg and http://i.imgur.com/QFZMpXf.jpg . This is kinda weird because it only happens like once every 1-2 hours or so. So i ended up using windows reset to reformat, even picked the option "clean the drive". After that the issue persisted so I contacted MSI to ask for help, which suggested I RMA my card since it was so new. Contacted Corsair which had me try different PCI cables/different ports on my PSU but that didn't help either and set up an RMA.
Dusted off my old 970 and put it in and low and behold.... same issue http://i.imgur.com/bxlDWGl.jpg .
I'm not sure where to go from here, brightside is I don't have to RMA my 1080ti I guess.
