I was wondering if I should upgrade my 2.3GHz Power Mac G5's RAM- from 1 to 2GB. I mainly use it for the internet (Mac Rumors mostly), e-mail, iTunes (lots and lots of iTunes), M$ Word & PowerPoint, and gaming (Doom III, rise of nations, etc... My sister also uses it on occasion (when I let her), mainly AOL & GarangeBand. I also use Virtual PC 7 w/ XPee Home Edition. When I run VPC it uses about half of my RAM- leaving a paltry 512MB free which in turn gets used by Mac OS and my running apps- leaving me with like 12MB of RAM free! VPC feels rather sluggish, so upping my RAM would allow me to give this app some more memory, hopefully increasing performance. I was looking at buying 1GB (2x512MB chips) of RAM from Crucial.com to stick in my G5. Any thoughts/advice are appreciated!
