I have a 2008 2.8GHz Mac Pro. It's grown a little long-in-the-tooth and it's time for a new Mac Pro. With that said, I'm on the fence with the graphics card options. I think that the stock D300s will smoke my ATI Radeon HD 5770 1GB card, but I'm not sure I should go with the D500s. I don't play games, so I probably don't need killer graphics. However, I do 3D rendering with DAZ Studio as a hobby, but again, I'm sure the D300 smokes what I'm currently using. Other than DAZ, it's all Pixelmator, RapidWeaver, Aperture, Eagle CAD, etc. Basic stuff that doesn't require killer graphics. So is it safe to assume that the D300s will be more than adequate for my needs or should I go for the D500s? $400 bucks is a lot to spend on something that I'm not going to take advantage of. I know in the past, the stock card in the Mac Pros were kind of "bare minimum" and that it was always recommended to go with the BTO option. Is the same true here, or the fact that I'm going from a 2008 MP to a 2013 MP make that assumption irrelevant?
