Hi to all. Im gonna upgrade my cpu tom, but im torn between two video cards. The Sapphire r9 270x Toxic 2gb and the Sapphire r9 270x 4gb. Im not much of a techie guy so the difference comparison is confusing for me. I mainly use my computer for photo editing in around 30mb or more each file and gaming like call of duty ghost and such heavy games. Here's alink for the comparison. Please help me by explainin the diff. Also only one 23 inch monitor at 1080p. Thanks
