2. Memory and a nVidia GTX 460+ card
3. No, not really.
How will the nvidia GTX460 help my work computer if it is only running CS4?
Would the upgrade to 24 (from 12) gbs of RAM improve my home PC that much? With the current newegg sale, it would only cost me $120 to get another 12gb of the same RAM...
Sorry, I thought you were talking about CS5+. For CS4, no updates/upgrades needed and the difference will be slight.
One more questions:
My work PC has ram that is set up as 6 X 1 GB (533 mhz).
I have found a Kingston set of 3 X 4 GB (1066 mhz). Would this set of ram (cause of its 3x4 grouping and speed increase) give a considerable performance boost? Is there a possibility the Dell machine MOBO would accept the higher speed ram?
For CS4 there is no need to add memory, siunce it is a 32 bit application and cannot use anything over 4 GB. If you were to use CS5, it would make sense to upgrade to 12 or 24 GB, but not DDR3-1066 for your home system, since that can be overclocked (the Dell can not) so DDR3-1333 or DR-1600 is much more attractive.
