having 2 videocards to choose from, I have this dilemma: one has GDDR5 but 128b while the other has GDDR3 with 256b ...

So, which counts the most ???

The combination of DDR5 and 128 bit generally has a slightly higher memory bandwidth than DDR3/256 bit.
This certainly should not be the basis for choosing a video card however. Memory bandwidth is just one thing that goes into how well a video card will work and it is far from the most important factor.
Tell us the actual cards you are looking at so we can tell you which is better rather than just telling us about the memory. Or better yet tell us your budget, processor, power supply and monitor's native resolution and we will tell you the best card you can buy for your system.

the cards are the following:

nVidia GT240 with GDDR5, 512MB/128b
nVidia 9800GT with GDDR3, 512Mb/256b

The 9800GT is better than the GT 240

They are both pretty outdated GPUs these days, so might be worth considering another card.

I would go with the 9800GT if only for its legacy. That thing was a beast of its time.
The 9800GT was actually just a rebranded 8800GT from the gen before, but because it was so powerful there was no competition to it, so Nvidia just renamed it. It eventually was beat by the 9800x2, which as the name implies was just two of the put together on the one board.

Though this was 2007/2008, by modern standards its quite weak.

Still got my old 8800GTX on a shelf, what a beast! :D
