In terms of overall gaming performance, the graphical capabilities of the Intel Q43 Express Chipset are significantly better than the Nvidia GeForce 6150 SE / nForce 430 64MB DDR3.

The 6150 SE was released over a year more recently than the Q43 Express Chipset, and so the 6150 SE is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Q43 Express Chipset.

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 6150 SE / nForce 430 64MB DDR3 and the Q43 Express Chipset have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The 6150 SE has 8.5 GB/sec greater memory bandwidth than the Q43 Express Chipset, which means that the memory performance of the 6150 SE is marginally better than the Q43 Express Chipset.

The 6150 SE has 2 Shader Processing Units but the Q43 Express Chipset does not have an entry, so the two GPUs cannot be reliably compared in this area.
