I use CS5 on a Win 7 Pro 64 bit machine that has built in GPU and graphics is the slowest item on my performance scores. The scores don't excite me much, but fairly often when I'm doing photo editing there is a very noticeable lag in graphics keeping up with my brushes, so I have been thinking of adding a graphics card. I'm not sure how much card performance I need. Most of the information I find on the web is directed to gamers. I have zero interest in computer games and I am poor, so I don't want to spend more than necessary to get a card that will easily keep up with editing activities. Anyone have any good recommendation?
