Really stumped here and looking for a bit of advice. I bought my first 270x a month or 2 back and i liked it but one of the fans had an issue so i just refunded it for now. Im looking to get another MSI card and do a 2 card setup. I really loved the way that the 270x Gaming Edition performed so i think that ill go back with another. I am upgrading my whole pc after i get my taxes this year which so far consist of my current processor which is a Intel i5-3330 and this is using a socket 1155, that leaves me with a MSI z77 mobo. To my knowledge this will support 2 video cards which will either be 2 hawk edition 2 gig cards or 2 gaming 4 gig edition cards. Will the extra 2 gigs help the gaming edition over the 2 gigs of the hawk? From my nooby eyes the core specs and memory specs arent that different other then the 2 gigs. Are the 2 270x 4 gigs a better choice?
