which one is better,64 or 128 bit memmory interface of video card?

[ani123]

is there a very wide difference in performance between two video cards(both of 256mb)of 64 and 128 bit memmory interface?

Absolutely, there is a big difference. The 64 bit is not even worth considering. The 128bit is the way to go. 64bit cards are bastardized versions of the real thing.
