How slow is GT 430 1GB DDR3 (64bit) compared to GT430 1GB DDR3 (128 bit)?

I recently got an MSI N430GT MD1GD3 which has a 64 bit memory bus as compared to other models which have a 128 bit memory bus. I want to know does the 64 bit bus makes my graphics card's speed go down to right to half of that of the 128 bit model?

If not then can somebody provide a comparision?|||It actually means that your graphics card will only be limited sooner in terms of data transfer to the VRAM. 64-bit is really, really slow, and you will definitely notice it when compared to 128-bit cards. The place where you will most notice the smaller bus width is with post-processing of video, like anti-aliasing and vertical syncronisation. Yes, you have 1GB of GDDR3, but a 768MB GDDR3 card with a 128-bit bus will give better performance than it. If at all possible, have the card exchanged for a 128-bit card, you won't be disappointed. 1GB of GDDR3 VRAM on a newish GPU like the 430 has is a waste, it will never be used like it can.



EDIT: Uhm, Jack, most new card have a 256-bit bus. 512-bit is massive, and only reserved for the extreme cards on the market. Budget cards often have a 192-bit bus, which isn't bad either... :)|||half the memory bandwidth and considering most new cards have a 512 bit bandwidth this is incredibly slow i wouldnt go with anything less than 128 bit|||you won't notice the difference.
