Hi there, so I have a 2010 Mac Pro, 12-core 2.93Ghz with 32GB of ram and an ATI Radeon HD 5870 Graphics Card running Mavericks. Im looking for recommendations for a better graphics card, without having to: add an additional PSU. flash firmware or mess around with it in Windows to make it OSX friendly. lose my boot screen. Considering these limitations, is it worth investing in a newer graphics card? Will I get any speed improvements over the current card I have? What are my options? My main GPU heavy hitter applications are: Maya 2014, PhotoShop CS6, NukeX 6.3, modo 603 and no, I dont play games. One thing I definitely would like an improvement on is more ram on the card. The more the merrier I suppose. Mayas ViewPort 2.0 and nVidias new offerings in Mental Ray are especially GPU-ram hungry. Ive read through the various threads here on this forum debating Mac Pro GPU offerings and quite frankly, they are a bit of a daunting read for the likes of me. Hence this thread. Please be kind to me and thanks for reading.
