I currently have a biostar ta790gx and phenom 2.5 quad core be chip. My problem is biostar never fully supported the am2/3 lineup so I just cant bring myself to pay over 100 bucks on a used amd phenom II x4 965 which is the best chip I can make work (I think), also not supported but with fiddling can be made to work, just to extend the life of a relatively cheap motherboard to begin with. Not to mention it is now double the price to upgrade ddr2 ram over ddr3.
I have settled on the GeForce ti650 boost (most bang for current buck) but I really do prefer AMD chips because once again I feel I can get more performance for the money.
I now am so far behind on specs and tech when it comes to motherboards I feel like I will end up with a bad board.
I am upgrading to play current games decently and use the adobe design suite programs.
I have a excellent case with great ventilation, a newer 500w powersupply, I am buying a ssd to run the os, and at least 8 gig ram.
