Hi guys! I don't post often on the forum but let me say that it is an amazing knowledge resource. I consult it quite often. Thanks to all to knowledgable members who help us not-so-good-with-computers people finding solutions to our problems! Let's cut to the chase: I am a Photoshop user. I'm a concept designer (digital painting) using a 2008 octo Mac Pro and a Wacom Cintiq at home. Since about a year, I got a new 2013 Mac Pro (base model) at work. I can feel the age of my 2008 MP when going back home. It looks like the next Mac Pro (coming this fall) would be a logical upgrade to make. I am wondering what are the specs I should be looking for when building my next computer... As I said, I only use Photoshop to paint. Right now, I paint images of 4800 pixels wide by 2000 pixels tall... Anything above that on the 2008 feels sluggish...(lag between brush strokes made on the Cintiq and when it appears on Photoshop) The 2013 can take up to 6000 by 2500 images but more than that and the same thing starts to happen. All I need is a computer that will be responsive and smooth. Best case scenario, I would be able to paint at very high resolution (like 9600 by 4000 for example) using big textured brushes (that have dual brush mode on and so forth). I don't need it to be fast for rendering filters and other things like that... I don't really use that... Painting is the only focus of this machine. Basically, my question is: what are the specs should I be looking for? The number of cores doesn't seem to make much difference compared to the clock speed... Am I right to think that? does the graphic card specs come into play? How much ram is enough ram, etc... I would very appreciate your help and inputs as I don't know much about those things Thanks in advance, Vinc PS: Sorry if I made several mistakes in my text, English is not my first language.
