For those of you who are more versed on computers than I - I just purchased a new Dell PC, with Vista and 4 GB RAM. I'm using it solely for photography, and have NX and PSCS3 loaded - both are running smooth and fast, especially since I took out the McAfee which was hogging up everything. When I check the RAM, it shows 3096, not 4000. I asked the Dell tech (?) and he said this was accurate since 1 GB is attributed to Vista. I understand that point, but still don't know why the full 4 GB isn't stated as onboard. Being the suspicious type (or actually more accurately, the naive type) I decided to ask some people here, whom I trust to set me straight. Am I getting my 4 GB worth?
