In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7300 GT are massively better than the Intel 865G.

The GeForce 7300 GT was released over three years more recently than the 865G, and so the GeForce 7300 GT 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 7300 GT has 240 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 7300 GT also has superior memory performance overall.

The GeForce 7300 GT has 10.4 GB/sec greater memory bandwidth than the 865G, which means that the memory performance of the GeForce 7300 GT is slightly better than the 865G.

The GeForce 7300 GT 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 and the GeForce 7300 GT requires 24 Watts. We would recommend a PSU with at least 300 Watts for the GeForce 7300 GT, but we do not have a recommended PSU wattage for the 865G. The GeForce 7300 GT requires 11 Watts more than the 865G to run. The difference is not significant enough for the GeForce 7300 GT to have a noticeably larger impact on your yearly electricity bills than the 865G.
