In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9300 GE are massively better than the Intel 865G.

The GeForce 9300 GE was released over three years more recently than the 865G, and so the GeForce 9300 GE is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 865G when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 9300 GE has 496 MB more video memory than the 865G, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 9300 GE also has superior memory performance overall.

The GeForce 9300 GE has 8 GB/sec greater memory bandwidth than the 865G, which means that the memory performance of the GeForce 9300 GE is marginally better than the 865G.

The GeForce 9300 GE has 8 Shader Processing Units but the 865G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The 865G requires 13 Watts to run but there is no entry for the GeForce 9300 GE. We would recommend a PSU with at least 300 Watts for the GeForce 9300 GE, but we do not have a recommended PSU wattage for the 865G.
