Okay all, I must admit that I'm just VERY ignorant regarding the importance of the type and quality of video cards. I simply don't know whether I care about the card selection beyond the bad-mouthed standard NVIDIA card for my purposes. I do NOT do video, nor do I play games. I DO, however, use my computer for Photoshop, and will be using a higher end Eizo LCD monitor when I buy my mac pro. Will image QUALITY (in Photoshop or Aperture or Lightroom) be affected by the card? Is there a reason, for those types of applications, that I would need more than the base NVIDIA card? What are the maximum number and size of monitors I would be able to hook up to the Mac Pro with the base card? Since these are the Mac Pro options, tell me why I'd need more than the base. NVIDIA Quadro FX 4500 (512MB of GDDR3 SDRAM) ATI Radeon X1900 XT (512MB of GDDR3 SDRAM) NVIDIA GeForce 7300 GT(256MB of GDDR2 SDRAM) Thanks in advance for any thoughts.
