Whats the REAL FX5500-T128 memory bus?

Question

Hello everyone!
I already searched for the same question in the forum, finding several posts about it, and none of them is usefull, all have lies and insults, i just want the real information, without fanatisms. Im a proud user of a MSI K8N Neo Plat. so, im not going to bash MSI without a cause.
Here are the other posts i found:
GeForce FX 5500-T128
FX5500-T128 memory interface 64bits or 128??
I think the MSI lies: See the true 64 or 128 bits
Here an Admin posted a link
MSI GeForceFX 5600Xt-TD128 vs. GeForceFX 5500-T128
To the MSI USA site where MSI says NOTHING about the memory interface but he manages to QUOTE the site saying 64bit. Even when on the previous post everyone in the forum was saying the card has 128bit (except the actual owners of the cards --weird, eh?)!
Also, im going to quote the following statements:
Here, in the MSI MIAMI Site, it says the following:

Quote
# Performance
# Core de Gráficos: 256 bits
# Interface de Memoria: 128 bits.
# Tasa de Llenado: 1.100 millones de téxels/seg.
# Vértices por Segundo: 68 millones.
# Píxeles por reloj (pico): 4.
# Texturas por píxel (máx por pase de rendering simple): 16.
# Dobles RAMDACs: 350MHz.
So, there is NO ONE who actually knows the real memory bus on this card?
This is the official MSI Forum! There should be at least one person from the company crawling around! I cant believe that a forum hosted on msi.com.tw has no one from the company to clear out things like this.
Also there is some that say the card with 4 memory chips are 64bit, well, this one has 4 memory chips if you have a good look at the picture on the site above.
Another thing that misleads me (and several people) is that MSI usually call the 64bit cards FX(gpu)-T(memory) while the 128bit are FX(gpu)-TD(memory) (although the D, I think is more related to the DVI thing).
I was about to buy this card, and im really pissed off with MSI for not being clear on what they are selling, im emailing them right now to see if they had an error on the site or whats going on.
I really hope no-one takes this post as offensive, but i find all this very confusing (not to say disturbing)

elcuervito,
One way to find out exactly what you have is with RivaTuner. As an example, here is the portion data pulled on my Vid Card:
