Hi guys. I currently have an ASRock Z77 Extreme 4 with an i5 3570k CPU. Im planning on buying some G.Skill Ripjaws X Series (2x8GB) DDR3 1600 (PC3 12800) (if you guys think of anything better please recommend). I am currently looking for a GPU and I was looking at the gtx 770 but I see alot of different types\brands\models that I dont understand. I dont plan on OC anything on my pc so im looking for a GPU that is not for OC or works really well without OC. My plans in the long run is to double RAM, maybe add another GPU, change the pc case (Cooler Master HAF X) and maybe install a CPU cooler like the Noctua NH-D14. Any and all help on the GPU (or any other recommendations) will be greatly appreciated.
