Tuning and Benchmarking a Dell GX270 SFF P4 - Recap

I've run a series of tests on the 270 P4. Usually I run the test 3 times and take the middle score to avoid outliers. The base configuration with 1 MB of RAM and the integrated Intel 82865G video scored 86.1. Installing a NVIDIA GeForce MX440 AGP card but leaving the memory at 1 MB upped the score to 92.6.

I removed the NVIDIA card and ran the benchmarks on a config with 2 MB of RAM. It scored a 86.6.

Here is the detail:

I then reran the tests on the config with the NVIDIA GeForce MX440 with 2 MB of RAM and got a new score of 92.7.

The detailed benchmark is this:

To recap;
86.1 with original config (1 MB RAM, Intel 82865G integrated graphics),
86.8 with 2 MB RAM and the integrated Intel 82865G graphics,
92.6 with 1 MB RAM and a NVIVIA GeForce MX440 AGP video card,
92.7 with 2 MB RAM and a NVIDIA GeForce MX440 AGP video card - about a 10% increase.
