I have an older computer and looking to upgrade my video card because I am attempting to do some basic 3D in Photoshop and my current video card does not support hardware acceleration. I have two video cards I am comparing and considering. But it comes down to a few questions I have.

One card is 512MB and the other is 1GB in Memory, does that extra 512 in memory really going to make a difference that it is worth paying extra for (doubles the price).

Basically is the performance improvement going to be noticeable or it might be noticeable or not noticeable at all.

Are there other requirements that I should be looking into? Meaning The 512 Card has this which will make it better (or worse) because...

Thanks for any assistance in helping me understand =>

Please when you say "But it's twice as fast" give details and explanations as to how twice as fast is truly better (remember more is not always better)

Note: Both cards have the requirments for 3D in Photoshop which are:

  • supports OpenGL, a software and hardware standard that accelerates video processing when working with large or complex images, including 3D.
  • has at least 256 MB of RAM.
  • has a display driver that supports OpenGL 2.0 and Shader Model 3.0, which the GPU uses to perform rendering effects.

Here are my computer specs along with both video card specs:

Both the cards are really, really old. Like 4-5 generations old. –  Sathya Nov 19 '11 at 6:44

My computer is 4-5 generations old => I must use a AGP card and those are some of the best I could find for the price. –  Lynda Nov 19 '11 at 6:45

For exactly this pair I'll say

  • Emotional and qualitative assessment: Radeon!!! 6200 is low low-end in 6000 series of NVidia, 3650 wins even NVIDIA GeForce 8600 GT and NVIDIA GeForce 6800 Ultra in general rating, which in turn is much more powerful than ordinary 6200
  • Quantitative assessment: for the same memory type (DDR2) Radeon has more speed for memory (TBT!) and GPU and twice the width of the bus (only the latter implies a doubled data rate)

Size of Video Memory doesn't play game (I think, but can not assert) at all - even 512MB will work on big resolutions.

Check your current PSU and requirements for selected card before buy - AFAIR, Radeon will want additional power and 400W PSU as minimum (I may be wrong)

If I was looking for a replacement, then stopped on the ATI RADEON HD4650 –  Lazy Badger Nov 19 '11 at 13:47
    
Both cards require 300W and my power supply is 480 => Thanks for the information. –  Lynda Nov 19 '11 at 18:00
    
Also from what I could tell both the NVIDIA Cards are PCI-E not AGP. I do not have PCI-E Slot or I would be going with a PCI-E Card => –  Lynda Nov 19 '11 at 18:03
    
8600 and 6800 was mention only as comparison point, not as replacement –  Lazy Badger Nov 19 '11 at 18:12
