Hi, I've recently purchased a GTX 960 and frankly, it sucks. I've been playing games that should be easily running like overwatch or g-mod and its crashing every time without fail. I'm just wondering if its got something broken, maybe with antialiasing as I've had a few problems with that and textures. If it is a dud or broken some recommendations for a card would be great, or even whether I should get another one and SLI it.
