I have a Dell XPS M1730 and am running Sims 3, and Lightroom 3.6 (I think), Adobe Photoshop.
I'm wondering if upgrading my RAM to 8 GB would make a significant change on my computer? I know I would need 64 bit to make use of the extra RAM. Just not sure it's worth it.
Right now I have Windows XP Professional. I'm going to upgrade to 7, I think I can even upgrade to 8 (more of my programs are incompatible though) but another question is: Does Windows 64-bit pose any problems for drivers, plug in play or running 32-bit programs?
