Planning out a new PC build for photography (Lightroom, Photoshop), audio recording and editing (Audition, Sound Forge, Nuendo), and video editing (Premiere Pro, Vegas) in that order of priority. Considering either an nVidia GTX 670, 680, or 690 level card or a Quadro 2000 or 4000 workstation card. Having a hard time choosing so soliciting input on which way to go with why's or why not's. My biggest frustration with the way Lightroom runs on my current, very obsolete, PC is the lag in seeing changes to the image on the screen when making adjustments in the Develop module, speed of import or loading of images from disk is less of an issue.
