Going to be purchasing this within the next week. What can I expect with my setup? Hp Pavilion dv7 Laptop AMD A8 4500M Vision: quad core @2.4Ghz(OC'd to 2.67Ghz) 6gig DDR3 1666Mhz Ati Radeon 6750M 1 gig dedicated Standard 5400rpm HD I can run Crysis 1 on high settings with no lag, just wondering how I'd hold up with dayz considering how large the map is.
