gpu 128/256 bit

what does mean when a card has 128 or 256 bit?

I was looking through some gfx cards when I came across the radeon hd 5750 and it has 128bit as a Memory Interface?

The HD 5750 has a 128-Bit memory interface of GDDR5. GDDR5 has double the memory bandwidth over GDDR3.

If your looking at a HD 5 series get a 5770. If you don't have a lot of money then just go with HD 4770 instead.

Or a GTS 250. The 5750 performs between the 4830 and 4870. It's kind of hit or miss in a few games.

That is the bandwith of the memory, so 256 has twice the bandwith of the 128.wooooode

direct x 11 support is important, more and more games will start using it, if possible I would get the direct x 11 card.

I wouldn't get a 5750 though and there are going to be as many DX11 games in the next 2 or 3 years as there are DX10 games AND DX11 is backwards compatible with DX10.1, DX10 and DX9.
