I have chosen the following case and psu for upgrading my rig today. Eventually im going to upgrade my mobo and cpu and memory to DDR3 and possibly buying a second card of the same later down the line. I am wondering what i should choose Im kinda stuck between 650 TI Boost because its cheaper but I read somewhere that the 7850 is about the same on performance but faster overall and newer? will this make much difference? im looking to play pretty much all the big games now and for the next year or so on maxed out settings if possible. my monitor is 1600x900 and i probably wont upgrade that anytime soon.
