GTX 260 896MB vs GTX 260 1792MB

[hihiman1]

I don't know much about graphics cards in particular, so I need help on this decision. I do not need to know much about costs I just want to know the difference.
In this chart:
http://www.tomshardware.com/charts/gaming-graphics-charts-q3-2008/Crysis-v1.21,758.html

I see that the GTX 260 896MB will run crysis at 21.6 frames per second. If they were to test Crysis with the GTX 260 1792MB how much faster would the frame rate be? I am new to this so if there are any variables to this could you please elaborate?

Thanks to any and all help!

The GTX260 1792 will not be faster in any way shape or form. The GTX260 isn't powerful enough to use more than 1GB of RAM, so even on higher resolutions, it's RAM going to waste.

Now I'm sure some people will say you can run GTA4 better since you might be able to use larger textures...but naw man, naw...the power isn't there to use nearly that much RAM.
GTX260 ~ 4870 < GTX275 ~ 4890 < GTX285 </~ 5850 < 5870....

A 5870 is much more powerful than a GTX260, essentially 2x4870s (or 2xGTX260s) and it makes do with 1GB of RAM. That's actually a video card that might be able to use close to 2GB of video ram.

Be aware that the 21.6 measurement you're looking at is for two GTX260 cards.

For that particular test, you might see a little better performance with extra memory because they had anti-aliasing turned on. The extra memory doesn't make the card any faster, but it'll prevent too much slowdown with settings like that turned up. I would not expect it to surpass the pair of GTX280s, however. You will also likely see better performance than what is shown in the chart no matter what card(s) you buy, given that the chart is over a year old. New drivers help. So... today, just guessing, I'd say you'd average 30 or so fps through the whole game. Some painful spots will drop below 20. Plenty of the game will be smooth, though.

I have several GTX260's. One of them has the extra ram. In crysis at 1680x1050 the extra ram helps a lot. You can set 8aa and not have any stumbles or jitters. With the 896 card you get it without aa enabled. I don't check but I really don't think the frame rates are any higher though. That's not why the extra ram is there.
