U see, when u plan to put a Better PCI-E card u would need a good procy to get the most of of the PCI-E card
so, G965 will use x3000 GMA is good to run Vista as it will support DX 10, but not the best on board grfx with Gaming !!!!
1GB DDR costs around 3.8 to 4k + TAXin Kolkata, where as i am not sure about XFX 6600 but both should come under ur budget or 9k !!!
these 2 would go another 1 and half year !!!! after then u would need to have a good budget to overhal ur PC... !!!!
as with 9k u wont be able to get a X2 with a good Nvidia or ATI or AMD chip board too... !!!
Therefore 1GB + 6600 seemed logical to me.. !!
