Mike, even though XP sees 3-3.5 depending on VidRam i think its worth it, I was playing MoH:A last night and had process explorer in the background, the game alone was using 1.6GB of RAM, and thats before you count all the windows stuff running, including BOINC,Total use was more than 2gb. For 1nt has a bigger screen, that dell runs at 1920x1200, thus more pixels, so i would say with all the extra textures and stuff on screen his ram usage would be higher still!
Have a read of the link i posted above, This is the conclusion.....
2) 2GB of memory will be enough to keep all of today's games running quite smoothly. However, in light of Battlefield 2, and the Battlefield 2142 Demo taking up over 1.8GB of a 2GB system, there isn't much room left for other programs running in the background.
When i said ' But i cant see it making a massive difference tbh.' i was talking about 1x4gb or 2x2gb. Read all the post and dont quote out of context. If you had included the line of text between the two you did quote it takes on a new meaning....
