I guess that it could be worth the 760 if you want to ensure 120 fps for all the future updates since Minecraft is slowly becoming a heavier game to run each update. Also, it would be fine if your processor was a 3 GHz, 3.4 is well over enough to run Minecraft and Gmod and stuff. Also like what I had said before, you can buy 4 of 2GB memory sticks to lower the cost from 1 8GB stick. Also, if you are going to get and SSD, I would recommend buying it with the rest of the parts. You don't have to get a large one though, 120GBs should be fine. Just install the windows, office, antivirus, and whatever system program onto the SSD and then put all video games or other things onto the 1TB. That's all I really have to say. Good luck!
