I'm planning on upgrading my monitor shortly from a 20" Cinema display (1680 x 1050) to a 27" 1440p (2560 x 1440) model but I do also game on my machine (in OS X only) so although my Apple supplied Radeon 5870 1GB model has remained fine to date I'm sure I'll need to upgrade to something with more punch. I find that I'm happy with any playable frame rate - for me 30's and over as long as the quality levels are high - I'm not worried about 60fps and FXAA is OK for me. I do want to stick to something that runs on the standard power supply and two 6 pin power connectors and need a boot screen as my plan is to sell the 5870 to part fund the upgrade. If getting a PC card I would get a friend to flash it in their PC as I don't have or want Windows personally. The Mac Edition GTX 680 is still very expensive and PC GTX 680 models with the part codes listed in the thread on here are not coming up as often used as a few months ago and when they do they sell for more than I would like to spend for something that will have no warranty when flashing. The 7950 Mac edition is occasionally coming up at a reasonable price for a new card with warranty but have/will the drivers improve(d)? When the card was first reviewed there were cases of the 5870 besting it... Also I know the Mac edition 7950 is a non-boost model but can it be over clocked down the line?
