I know apps like photoshop & illustrator CS5 will use raw CPU power instead of GPU, but I was wondering, from the fact that things like zooming & 3D effects may take advantage of discrete video...
Does it do any good to buy prefer higher video memory (1GB over 512MB or if you will 256MB) when it comes to 3D effects on those apps?
Or Is it better to get a faster GPU to get the job done (let's say, for instance, a Radeon 6850 over a 6570, & this is just an example, but if it doesn't impact that significantly I guess I could stay on a 63xx-64xx range, considering I use this rig just for work, not gaming?
Thanks in advance!

If you use alot of apps that use CUDA (Nvidia GPGPU tech) then Nvidia is the one to go for
if you look at the apps you use alot of them like Maya and AutoCad for example
will strongly recommend only workstation graphic cards not gaming cards
due to the drivers for Quadro being optimized for OpenGL and those apps
remember drivers for gaming cards are optimized for games not workstation apps
really depends on the software you use and also if this is for home use or professional
for professional use it is basically mandatory to go with a workstation card
even if the gaming card has better specs the workstation card can outperform it
in apps like Maya,Autocad etc
for just basic Photoshop than a gaming card is fine
Me personally I use a HD 5670 with Cyberlink PowerDirector which utlilizes the ATI Stream GPU acceleration for rendering and encoding
ATI Stream is the equilavent to CUDA
I can render a 10 minute video to disk in under 15 minutes with a Core2Duo 3ghz and HD 5670
which for older hardware isnt bad
I use it for editing home movies for customers (adding music,titles,transitions,wipes etc)
workstation cards can be quite expensive so depending on your need
amateur vs professional and apps used
determines whether a workstation GPU is needed
I would stick with a 6570 or 6670 or 5670
really the lower cards like the 5450 and 6450
are mainly home theater cards and multi monitor cards
really newer onboard graphics are getting close to the performanc of a 54xx/64xx
