I am looking to upgrade the ATI Radeon HD 4870 that came with my 2009 MacPro. I got the OK to spend around $300 for the upgrade. (would have to sell the 4870 afterwards though) Primarily I am looking to run my three 24" displays running at 1920x1200 each. Not interested in gaming just Graphics work. Mainly Photoshop. (Large Files) I was looking at the ATI Radeon HD 5770 on Apple's website. It looks like this would do the job. BUT, I thought I would try to get some advice to see if there are any other options. I would need something that would install/work just as easily as the 5770, have 3 ports (preferably DP or MDP) and cost around $300. Any input would be greatly appreciated.
