I want a good but cheap gaming desktop 600$?

I'm not very smart with computers so I don't want any "build your own pc" things. I will mostly be playing elder scrolls online, skyrim, minecraft, and maybe some others. I don't know if it makes a difference or not but I would be modding some of my games. I won't be using it for anything but gaming and watching movies. I want to know anyones opinion on the best gaming computer that I can get for around 600$ or less and where I can get it.

You won't get a good gaming desktop for $600.

AMD Black Edition - AMD FX 3.3 GHz Processor - £80
MSI 970A-G43 - motherboard - ATX - Socket AM3+ - AMD 970 - Socket AM3+ - £50
EVGA GTX 660 FTW Edition GPU - £150
8GB Ram of your choice £80
Hard Disk drive - £50 to £80
Case - Find one to fit the remaining budget

Sorry its in pounds I'm from the UK but with exchange rates applied this should be in your budget and will be a very solid setup. It is very similar to my current PC and I'm able to achieve full settings on the games you listed.

Here are a couple answers.
