So my mate has a 5770 atm, it's not terrible he plays with a 27" 1080p monitor and a second monitor at some lower res ~720p ball park is buying a 2nd 5770 going to be a value for money upgrade? or would he be better off spending more on something like a 6850. I don't think he minds not having maxed out settings but at least medium to high on new games at 1080p is what were looking to accomplish. atm a 5770 looks like it'll cost around $100. He's just spend $600 upgrading to an i5-2500 rig and trying to keep this as cost efficient an upgrade as possible.
