I like to know, do I have to purchase 256 mb ram of graphics card or can I achieve a near about performance by assigning 128 mb of my RAM to graphics card(128 MB) from BIOS.
getting 128MB would be quiet difficult i say.But yeah,256MB version is still available at few outlets,if you can try.6800GS is a bit scaled down version of GT,but with high end fabrication process.
