I have a 5dm3. It runs great on XP pro (probably XP, also). I used DPP. You could use lightroom3, works great on XP. Some of you are adding expenses you don't need. Now if you have Win 7 use DPP. I don't know the memory requirements of lightroom 4 but it would surprise me if it takes that much, but it could. Wait, my laptop process my 5dm3 and it has 2 or 4 gig memory. I have lightroom 3 but usually use Photoshop 5.5 on the table top and Photoshop 3 on the laptop. Lightroom 3 works on both.
I don't think the 5DIII works with LR 3 and new Adobe products including LR 4 won't work with XP Pro 64. For those that are used to using LR exclusively, adding DPP into the workflow is a significant factor.
