I've already ordered this monster monitor along with a keyboard and laptop stand. My worries though are is how well my 13" MBP can push this thing in "closed" fashion. Sure it has the Nvidia 320m and I've upgraded the memory to 8GB, but just wondering if performance will suffer in Photoshop and perhaps some light gaming (Halo CE, Bioshock). I know the internal/shared GPU may not have the muscle to run native resolution with no FSAA but for average desktop use, is this wise? Or should I just buy the entry level iMac? Between the two purchases, is only around $200 more for the iMac. But after spending time and money on my 13" MBP, I want to make the most of it (massive workspace at home and great portability on the road) Anyone using the 27" ACD with their 13" MacBook Pros. If so, any impressions on it's performance?
