YUP Nvidia chipsets pero the 6100 nforce chipsets based are crap daghan ug issues like thermal and when using the builtin mo garbage display cya etc... been return and replaced my mobo 3X still the same so ayaw palit ana get the latest 6800 or later. Better ayaw nalang pag nvidia chipset instead get ATI like M2A-VM w/c is best for your system. I think it has a good Integrated GPU on ASUS M2A-VM mobo.
You can both use NVIDIA or ATI GPU on PCIEX card backward compatible rana cya so nothing to worry.
