Conclusion and Final Rant
Well, after all the testing, the results are in and what can we say? The i845G is a rather impressive chipset so long as you use external graphics. Internal graphics are more than a little disappointing, especially when Intel claims high performance technology, and yet when tried in 3D applications and gaming situations, it fails to deliver even reasonable results.
3DMark2000 was the only benchmark that I was not too ashamed of for the Integrated graphics, after that, I totally lost hope. When running off board graphics (our GeForce3 for example) the i845G is as good and even better than the i845D predecessor. With memory scores consistent with the performance curve, 3D scores running the same as i845D boards using 400MHz FSB, we see that the i845G does have huge potential to become a super chipset for the Pentium 4. Only some very foolish decisions have held it back, i.e. no DDR-333 support and only 4 bank rather than 6 or 8 bank memory.
Intel Extreme graphics is ok for a value (I mean extreme value) system as its 2D functions are rather impressive. DVD playback was flawless, Intel's new DVD acceleration appears to work. TV out has gotten better with the i845G, though it is still nothing compared to ATi's, and workstation requirements don't reach the IEG's level of performance, so its ideal for those el-cheapo workstations.
On the whole, the i845G is definitely one that needs some work on the internal graphics, but if you want a power board and are considering off board graphics, you won't go wrong with i845G in this respect. Lets see some more power Intel.
External and Internal Graphics support
Native USB 2.0
Internal graphics very slow
