    CPU and paintbrush /blur brush @ 300 pixels wide

    soundgrafik

      Hey guys I've been a Photoshop user for close to 15 years. I have ver. CS2 and a AMD Athlon 64 X2 Dual core CPU 4200+ 2.21GHz CPU /1GB RAM (6 years old along with the version CS2 running WinXP SP3) I plan on upgrading this year my hardware, OS (to WIn 7 64-bit) and the Adobe Production Premium suite to CS6 (After upgrading to CS5.5 since I am ineligible for the upgrade from CS2. )

       

      One of the things that has always bothered me in Photoshop CS2 was when I set a paintbrush or a blur brush to 300 pixels wide and I'm working even on a small 4x6" 300dpi canvas If I make a brushstroke it takes seconds to make a rendered stroke. I plan on doing digital paintings with a Wacom tablet 8x10, 11x14, 16x20" in size with Photoshop CS6.

       

      I read that as of 2008 CS 3 Photoshop will use the GPU for rendering/processing some effects. Is this true for PaintBrush and blur tools?

       

      Granted we are talking about a 6 year old mid-level CPU and now new technology but I would like to know along with using 8 GB RAM

      Will this 300 pixel-wide brush lag totally change with a Ivy Bridge Intel Core i5-3570K Ivy Bridge 3.4GHz    Quad-Core?

       

      Is there a significant difference when using Photoshop with a Ivy Bridge Intel Core i7-3770K Ivy Bridge 3.5GHz    Quad-Core since both chips are multicore which Photoshop does use?

      I'm trying to choose my new build and figure out what CPU to get since they are $110. difference. Is is night and day with most of the CPU intensive stuff on Photoshop?
