To see if your card is 128bit or 256bit. Is there a program that could do it. I mean i tried every thing from 3dmark to sandra and nothing would give me how many bits is my card. Any help is greatly appreciated. Oh and no, I dont want to check it online cos it clashes with my 6600GT Leadtek make. I want to make sure in an active scan. The reason behind this is that the salesperson claims its 256-bit while, online it states its 128bit. We have an agreement, that if i could prove him wrong, I could refund it for a 6800gt. Longstory short, Just answer if you ever saw some program report the memory interface.
