I'm planning to build a gaming pc since my laptop recently died. My budget is about $500, but I may be able to stretch it to just over $600. I plan to make upgrades in the future. I have a mid tower atx case, optical drive, windows 7, monitor, keyboard, and mouse so no worries there. I would prefer to stick with intel i5 cpu (3570k and 7870, but it may be too much). I need wifi connectivity, but I can do without it for now. I could add a pci card down the road. I don't plan to do any sli/crossfiring. Some games I play are diablo iii, starcraft ii, cs:go, left4dead 2, bioshock infinite, tomb raider, watchdogs, wildstar, and battlefield4. I'd prefer to play them at 60+ fps. Any help is much apppreciated.
