Pretty simple question... I am purchasing my first GPU for my newly built computer. I am wondering what one I should get. I am stuck between the r9 270 and the r9 270x. I have a budget of $260. If I get the r9 270, I will most likely get another stick of 8gb RAM. I will then have 16gb of RAM. I use programs such as cinema 4D and Photoshop on a regular basis. My CPU is an AMD A-10 5800k. Any help?
