yes

the price of a 512MB X1800 XT is actually $400
it's the 256MB X1800 XT's that cost $300

Not like 512MB makes a big difference over 256MB. Not yet anyways.

No way in h3ll, haha. The X1800XL can't even keep up with the 7800GT, much less the 7900. Wow, some benchmarks out there...

I direct you to the 7800GTX-512MB. Its a testament to the power of the chip that it benefits from 512MB memory.

The 7800 GTX 512MB gets the performance from the core clock speeds and the speed of the RAM, not the amount (550mhz core, 1800mhz memory versus GTX 256MB's 430mhz core and 1200mhz memory. It's like back when they had some 512MB 6800 GT/Ultra that performed almost identical to the 256 counter-parts, helped a little bit in Ultra settings Doom 3 though.

Misinformation should be a crime.

Here is a good review of 256MB vs. 512MB. But note that the computer has 1GB of RAM. In the normal resolutions that is used by most gamers (10 x 7 and 12 x 10) it showed little improvments. But in 20 x 15 resolution, the extra RAM shows a lot of improvement, but only a few people will play games at that resolution.

Now in ultra mode in Quake 4, there is an improvement in performance. This is because id loves to put very detailed and high res textures in ultra mode. In FEAR they perform the same in normal and max settings but only on max settings in 16x12 res that the 512MB shows it's strength.

They concluded that on a 1GB machine, anything over 100MB of system memory usage starts to slow down noticably. This usually happens in very high resolutions that most gamers don't play at. But if you have 2GB of RAM there would be very little circumstances where there is sytem slow down.

By the end of this year, IMO, more VRAM will start to be used; but 256MB will still play games fine in lower resolutions like 10x7. 512 RAM does help in some cases, but isn't worth an extra 100 dollars when having 2GB will play it fine.

512 does not make much of difference at the present time, but Oblivion should give us a better idea of RAM usage in the future.

The 7800GTX 512MB beats the 256MB version in games that have the same memory usage (which is most games in normal res) becaue it has faster clock speeds, end of story.

Have you looked at the benchmarks? The X1800 XT beats the 7900GT at high resolutions in nearly all games.
