hello I'm planning on building a pc for imaging mainly photoshop and corel painter x3 it is unlikely to be used for gaming. I want something that will give the right configuration options. i saw a video on the gtx 560 and saw the stretch options and I'm confused. could i use two of these cards or similar and maybe stack/ stretch if you understand my terms, 5760x1080 on top of each other as 1 monitor for the wall then 1920x1080 side by side as 3840x1080 my pc is not finalised
