The i5 build costs £60 more, should I get the i5 build and upgrade the gpu later on, or get the other one, I will be using it for gaming such as terraria, dota 2, maybe civ 5, so nothing too demanding I'm not too bothered about graphics settings as long as there's playable fps, so will the HD6670 cope? I'd rather get that build due to it being from a trusted retailer. (No comments saying buying from shops is stupid, do everything yourself blah blah blah please, these are the 2 options) Thanks in advance
