Folks, firstly I know that the speculation over the 2010 Mac Pro's (potential hex-cores) has reached fever pitch but I've also seen talk that it could be June before we see a product refresh here and I'm honestly not sure I can wait that long .... or can I? My current equipment, used mainly for photoshop and other photo work, is a Power Mac G5 (model 11,2) 2.5Ghz quad, 8Gb DDR2 667MHz RAM, and a GeForce 6600 256Mb VRAM graphics card. I'm finding my machine to be a little slow these days, especially having checked out the more recent machines available in store. Even opening applications like Excel seems to take an age. In addition, support for non-Intel machines is waning when it comes to the latest software (Lightroom 3 won't work on a non-Intel Mac for example) I would very much appreciate some advice on potentially purchasing the current Mac Pro offering with a 2.93GHz quad core with 8Gb 1066MHz DDR3 RAM. If I do, is it worth my while spending the extra £'s on ATI Radeon HD 4870 512MB graphics card over the standard NVIDIA GeForce GT 120 512MB just for photoshop? And what about if I decide to install windows at a leter date so I can load and play FlightSim FSX? What about the extra £'s to go from 2.93Ghz to 3.33Ghz? Alternatively, given my potential uses as specified, do you think there are really that many gains to be had waiting for the 2010 hex-cores or will I notice enough significant performance gains over my current equipment with the 2009 Mac Pro as detailed? Any info you can offer would be greatly appreciated .... thank you in advance!
