Well after being away from pcs for a good long while and going to consoles I've been biten by the urge to build a gaming pc. Last time I built a pc I got the biggest baddest video card out... A 128MB Radeon! So yes it's been awhile... But after watching videos of games like dayz ect I want to jump back into pc. My wife has a Asus store bought pc, duel core 2.6 ghz, 6 gig ram ect, I found an older GeForce GT220 card for free and slapped it in... And well for counter strike it's not bad but dayz is horrendously choppy and just not a good experience. So for around 5-600 bucks what would be a good build to where I can play games such as dayz and arma ect and enjoy it? All the new tech out with duel vid cards and sli crossfire ect ect it get confusing for someone that's been out of the loop for awhile...
