Graphics are definitely the weak spot for the Dimension 3000 as it is for most budget systems. It uses the Intel Extreme 2 integrated graphics which has very limited 3D capabilities. To make matters worse, the system lacks and AGP or PCI-E slot for a graphics upgrade.
Your stuck with what you got basically. To upgrade graphics to play the games you listed, you pretty much have to build a new system...
