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

The current AMD R9 series have not been reviewed with glowing comments - but not bad either. Have you considered equivalent nVidia cards? Quality-wise, they are generally more positively reviewed. A good site for this (mostly Linux-oriented) is Phoronix.com. Here is a review of the R9 270x: http://www.phoronix.com/scan.php?page=article&item=amd_radeonr9_270x

Their opinion was for Linux gaming it is a good choice at the $200USD price level.
