In terms of overall graphics performance, the GeForce 9300 is in a class by itself on the Intel side of things. While the G45 struggles to maintain any kind of playable frame rates in the games that I tried and crashed 3DMark Vantage altogether, the GeForce 9300 was able to finish the test and have decent frame rates throughout. The GeForce 9300 chipset is 20% faster than the Intel G45 chipset across the board. By this performance metric, it is likely that the faster 9400 boards will outstrip the G45 chipset by 35% or more across the board. This is a very impressive feat for an integrated graphics card to say the least. Had the GeForce 9300 and 9400 come out when the G45 launched, Intel might have had a real problem. Intel is rumored to have a new CPU coming out for the high-end and we'll see how that translates with integrated graphics at that time.
