First of all I'll start with the disclaimer that I know absolutely nothing about video cards. I am currently using the Intel HD 4000 built-in graphics display of my 3570K. It works OK but I am thinking that I would like to have a discrete card.
I'm not a gamer so don't need a high end, super whammy card, just something for general internet videos and occasional Photoshop work. I am looking at the two cards listed below and would like some opinions on which way to go. My ASRock Z77 Pro4-M has PCIE 3.0 support (the GTX 650) but I'm sure that for my purposes PCIE 2.0 (the GTX 550 Ti) would be fine. These cards are within $10 of each other so price is not a factor.
