Will this run dayz standalone and minecraft at 60 fps?

Someone done an FPS test with that GPU on YouTube, it can be found here - - the results can also be found in the description of the video. I would also not recommend that power supply as it is not from a reputable brand, stick to brands that are known for making good quality power supplies such as Corsair. Hope this helps answer your question!

You're joking right? Do you know how low spec minecraft is?
That system is a over kill, but that graphics card is a waste, it'll be bottlenecked by that CPU. I've got a better CPU than that and a worse GPU. I have the GTX 660 2GB Palit, and a AMD FX 8320 Overclocked @ 4.23

The AMD FX-6350 or even the FX-8320 would be a better choice for you, since they have more cores. Still, it would be able to play everything on good settings. The GTX 770 is a great video card however, but if you cut a little on the gpu, maybe a GTX 760, or an R9 270x, you'll get a well balanced system between cpu and gpu computing power.

Power supply is strong enough to handle both of those beasts.
