Internet speed depends on your connection not your PC. That being said, building a PC is superior. You will not find a $750 PC that can run DayZ smoothly. Alienwares are great, but they're overpriced. We can give you a parts list and your friend could assemble it.
Ok, sounds good. COuld you please give me a parts list? and what would be the ballpark estimate oon how much buying all the parts is going to cost? Much appreciated.
