Intel D101GGC Motherboard PCI Express compatibility... (by 2 users)

I meat a computer guy who has knowlege in this area, he told me that INTEL D101GGC is a fail motherboard, you can add any NVIDIA graphics fro eg. Geforce 8600GS which is the cheapest and best fit. But again he ask me not to buy that cause our board has onboard ATI X200 and also told me that our motherboard is not manufactured by INTEL but by ATI it self. so NVIDIA graphics will not work properly in our motherboard....
He asked to get ATI graphics card for our board which he is going to tell me in a week or so, but i prefer rather than buying a card he asked me to change the motherboard from ATI to INTEL 945 too good which is compatible with our old processer in my case duel core 2.66GHz and again is origanal INTEL and supports DDR2 RAM which i again new and speedy and then you can buy NVIDIA Geforce 8600 GS Which will cost you 3200Rs for INTEL board and 2300Rs for the Graphics card and a thousands for 1GB of DDR 2 RAM, which will come to7000 Rs. and your computer will be as new...
