Exactly what video card are you talking about?

PCI or PCIe? Generally the 128 refers to the capacity of the memory that's onboard the video card - where the 32 bit refers to the width of the data bus (and, thereby, it's ability to transfer data from one part of the computer to another).

i understand what 128 bit means, but what i dont understand is just how much is that making a difference. is my motherboard limiting my cards potential by a lot or a little?

The video card is a PCI video card, so yes, it will be limited by the PCI slot capability, but, somewhat, that's simply because of it's design, and there is nothing you can do about that.

An AGP card, in general, would have faster throughput, and the PCIe cards even faster.

If you do not have an AGP or PCIe slot in your system board, then a PCI video card will be best choice for you.

Your question - "Does it realy matter?" is somewhat moot, in my opinion.

A better question is - "Do you have a better choice?" (Regarding type of card)

I suspect, at this point without knowing your system board, that the answer is going to be "no".

What is your system board? What video card are you using now?


I know you think you understand what you thought I said,
but I'm not sure you realize that what you heard is not what I meant!

i know all about how PCIe is better and all that. but the games i play are "old" games from no later than 2003. so they are not the most advanced power hungry games. my motherboard only has PCI slots. even though i understand that PCI isnt that great, it will do for now and i dont want to go through the troubles of getting a new motherboard.

i just put in the new video card 2 days ago. i had onboard graphics up until now. the video card made quite a difference in most of the games. i was just wondering (not that i can do anything about it) if the bits make much of a difference.

The thing about 32 bit this and 128 bit that is that they are measurements. In this case they are measurements of two completely unrelated things. 32 bit is the width of the PCI interface, and this may limit your cards communication to the rest of the system. 128 bit is the width of the memory interface between the memory and the graphics processor, both of which are on board the card. The memory interface is not limited by the PCI interface because it doesn't pass over the PCI interface.
