Gx2 and GTXs have the same amount of ram...so how can you say it will kick its ass? its just slightly more overclocked than the Gx2.
I'm an ATI guy so I may be wrong: GTX 768MB memory, GX2 1 GB. So 2 GTX's would be 1536 memory compared to the 1 GB on the GX2.
I think that is what we are trying to say about the memory. The extra 128 per core leads to higher FPS when running filters or high res. There are also other factors I'm sure, but look at all the other 512 MB cards and their performance at the 1920x1200 and higher res.
A little off topic, but I'm finding it hard to reason the rationale behind the 512 MB barrier on cards these days. I'm sure cost and practicality for most users are the main reasons, but when we're talking about high-end cards I see no reason not to step up.
Do SLI or CrossFire double the memory ? This is one the questions that many people make mistake understanding it . The answer is NO , SLI or CrossFire doesnt double the memory , You have a 512MB card , adding another card wont make your memory 1GB, it still will be 512MB Another example : A game needs 512MB card to run at maximum settings , and you have a 256MB card , and you think if you add another 256MB card , your memory will be 512MB and thats not true.
You may see this mistake in many sites.

And then there's the question of image quality. Even in games that do properly support SLI, the GeForce 8800GTX often outperforms the 9800GX2 when anti-aliasing and anisotropic filtering are enabled at high resolutions. This is a weighty consideration in a system that's designed to provide the ultimate graphics quality; as a result, we might have picked the 8800GTX even if the 9800GX2 had been available at decision time.
I recognise that last comment from Tom's new high-end system. It's true that:
1. The 9800GX2 impresses people with super-high frame-rates at low resolutions.
2. Nobody needs super-high frame rates that are faster than their monitor's refresh rate.
3. The 8800GTX beats the 9800GX2 at higher resolutions, AA/AF, and detail settings.
Easy conclusion: The 8800GTX wins where we need the extra performance, while the 9800GX2 wins at settings where the higher frame-rates are meaningless.
The 9800GX2's "superior performance" is like a scam, it's like saying "This car hits 8,000 RPM in Second Gear, but this other car only hits 6,000RPM in every gear" when both cars have the same gear ratios. In the gear that matters (high gear), the "slower" engine wins.
wait a sec, SLI/CROSSFIRE doesn't dobule the Memory, 2x 8800GTX = 768MB memory:
I guess I shouldn't post while drinking.
The effective memory is still 768 per core. I think I was just trying to state that the GTX has more memory than the GX2 cores do. I must have had diarrhea of the fingers last night.

the memory in the graphics system do double!but the amount of memory which per card or core have for cache the pre rendered frames stays the same.and the GX2 have 512/core where as the 8800GTX have 768/core.makes sense?

Indeedy, which if you're going by Nvidia's (and ATi's) memory on their dual GPU cards means teh GTX has 1.5Gb of RAM as well.
Thats right, HD 3870X2 has 1 PCB(HD 3870X2 a single card ) and has 2 HD 3870 on it and each has 512MB memory so the total memory HD 3870X2 is 1GB and as u know
But its different for example for 8800GTX, a 8800GTX has 768MB memory and if u SLI a 8800GTX it stil will have 768MB memory
Its all memory limited(more so with AA and all that nice stuff on)...toms did a review to show this too. I am sure the 384 bit memory controller helps somewhat...

True, but unfortunately that 512 x 2 memory in reality only works as efficiently as 512mb.
The Ultra with 768 has better memory performance than a board with 512 x 2.
That is what I think sucks.
Screw the dual GPUs and just give us an 8800 or a 3870 with 1GB RAM or even more.

Dual GPU is a revolution, don't forget that the dual GPu leads to Quad Sli which no card has up till now out of the 8 Series. So it will be the first Dx 10 card that has Dual GPu from the 9 Series.
Since the 3870 X2 was really bad at filtering I think the 9800 Gx2 is a welcome. I think 2 gigs or 1.4 gigs would've benefited it alot more.
There will be a 2 gig version I gaurantee it just like the 8800 GT 1 gig.
I must agree. I've been ranting about "high-end" cards stuck with 512 MB of memory for a while now. Memory is cheap, and these cards are not. I would pay the extra $20 for another 256-512 MB of memory.
Agreed. As a 9800 Gx2 owner I would suggest you wait for another version of the Gx2 to come out...because not even the 9800 GTX will cut it (it only has 512 ram as well)
In my defense, I really don't game at anything higher than 1280x1024, but I'm really frame obsessed lol So i like having over 70 in every game. God help me with CRYSIS! lol

according to the TH review the 9800gx2 wasn't much better than the hd3870x2 when it came to filtering either...dude that is so much overkill for 1280*1024..why not just get a bigger monitor?
The 9800GX2 did spend a fair amount of time ahead of the 3870x2. and in some games like unreal some filtering did not even work. So i guess thats what is meant.

Agreed. As long as its a reasonable ammount of GDDR3 RAM and the card is strong enough. May be the declining RAM prices might help. But you would never want a card like this: http://www.ebuyer.com/product/140112
Btw, can nVidia use GDDR4?
