Why? Seriously, he HAS to get a 770, because YOU said so...and on what do you base the assumption to tell someone what he HAS to do? I'm just asking here? DO you have any idea what this systemm is going to be used for? I don't, I looked at the components and know it will be a good all round build that should fill whatever needs he may have. It's threads like this that drive me crazy, everybody and their brother telling people what they HAVE to get, what they NEED, etc...For all anyone knows his biggest need may be for pulling large data sets off the drive, video, images, GIS data, CAD, etc....yet knowing nothing you impose and start saying what he/she has to do...from the looks of your suggestion it's strictly aimed at gaming, yet only 4GB of DRAM?
And I too used MSI for years, until quality started to slide, back around 2007/8 and got progressively worse, sales went flat and started sliding while Asus, and GB forged ahead, and the ASRock got it's presence known and in basically 3 three years passed MSI as the number 3 in sales where it remains (and continues to increase sales) while MSI continues it's backward trend.
