Thanks for the replies
@Jthill -Budget is maximum $700. Thats with OS and everything.
1. I tried to put together a decent rig on pcpartpicker,(http://pcpartpicker.com/p/CB4S)
and what I came up with is a Phenom II x4 with a 7770 that I would have to put together for about 640. So I thought I'd put this out there to see how it would compare.
2. For Dayz? From everything I've read a 7770 would be fine for Dayz, as it is a extremely CPU dependant game and I am not really trying to future proof this PC, just get a good setup to play Dayz and maybe upgrade some pieces next year.
3. I am not really interested in overclocking. I am just extremely new to PC gaming, I have never built one, and not sure I should be messing around with something I don't fully understand.
Thank you guys for the help. Really, keep any suggestions coming because I am looking to make purchases today.. hopefully!
