Hi, I own an iMac i7 24GB memory (Late 2009) I have upgraded the hard disk and memory, the only downside is the graphics card ATI Radeon HD 4670 256MB, just wondering which card will fit or replace the existing one, and if so, will I see any increase in performance? I use the computer to browse the net, listen to music and videos, also like to download the photos from the space from the nasa, which sometimes are really big, will it be worth the trouble to do the upgrade, any suggestions? Thank you.
