Which pc should I buy?

[CoolidIP]

I have a lower budget for a desktop pc right now about anything under $600. I've been wanting a good computer where I can do everything a a I like to do such as store files, broowse internet, watch movies, and an occasional game such as minecraft. I know these are all easy tasks, but I want a good cpu and don't want my computer to be too laggy like my current. I've done some research and these are the three I have been considering. If you guys have any thoughts or opinions or any other ideas let me know. I can also purchase other components to upgrade the current ones.

I'll pick the HP Envy and upgrade the graphics for this reason: http://www.google.com/search?q=intel+hd+graphics+2500&nord=1&rlz=1C2CHFX_enUS518US518&tbm=isch&tbo=u&source=univ&sa=X&ei=il3uUrKXA8mkrAH7kIGgDw&sqi=2&ved=0CDUQsAQ&biw=1680&bih=913#imgdii=_

When you upgrade the graphics (add a graphics card in this case) you may also need to upgrade the PSU because off-the-shelf computers have PSUs with just enough power to run the system.
