NVidia GeForce FX 5600XT 256mb, What compares??

[CMP 2003]

Ive read through a couple threads concerning vid cards, and not suprisingly some of you guys are very knowledgeable when it comes to vid cards.
Anyway, I built a pc about 4 months ago, and bought, what I thought to be a really good vid card, Aopen Geforce FX 5600XT 256mb

I have a couple questions, What does this vid card compare to, alot of these chipset models have 128mb, and thats my second question, what kind of an advantage do I have over a 128mb 5600 card?

Thanks ahead of time

With a 5600XT, not a huge advantage (over a 128MB 5600). Your card's performance is in-between a 5200 and 5600 non-Ultra.
