Memory bandwidth numbers are nice and high, 7200MB/s from a stock system is definitely very nice to see. Overclocking to 1104 MHz memory does not boost bandwidth numbers much because the processor's memory controller is running near stock speeds.

PCMark05 is a premium tool for measuring both normal home use and simple 3D performance of the latest PC hardware. There are 11 system tests - each one is designed to represent a certain type of PC usage. By running these tests, PCMark05 stresses the components in a similar manner as they are stressed in normal home usage.

PCMark05 shows similar numbers as the other benchmarks, it cannot differentiate between the 1GB and 2GB kits. If your computer is simply doing office type tasks, 1GB of system memory is still plenty.

3DMark05	Source: FutureMark

3DMark05 is best suited for the latest generation of DirectX9.0 graphics cards. It is the first benchmark to require a DirectX9.0 compliant hardware with support for Pixel Shaders 2.0 or higher! By combining high quality 3D tests, CPU tests, feature tests, image quality tools, and much more, 3DMark05 is a premium benchmark for evaluating the latest generation of gaming hardware.

3DMark05 does not benefit from more memory, but the CPU score does increase nicely due to the increased memory bandwidth from overclocking.
