two 9800gtx's vs one 9800gx2

Neither.

2 x 8800GTS for ~£330

or if you want the super cheap option that gives about 90-95% the performance of a GX2

2 x 8800GT for ~£235
 
Well if you already have an SLi mobo then SLI is the way to go, like the above poster pointed out, I on the other hand would get a GX2 so i could keep on the Intel chipset.
 
Does the 9800gx2 not beat the (8800gt 8800gts and 8800gtx in sli) on most new games by like over 25%?



(Making a whole new PC btw)

GX2 is slower than SLi 8800GTS's.

SLi GTX's will beat it in high res lots of AA.

SLi GT's will be about 90-95% the performance of a GX2.


A GX2 is just two underclocked 8800GTS's strapped together.


As Raven says, the main reason for going GX2 is so you can keep the better Intel chipset.
 
Hmm not 100% sure on benchmark tests to me it seems that the 9800gx2 comes on top most of time aslo new drivers will come out that will enhances gaming performance no ?
 
8800GTS, 9800GTX, 9800GX2, 8800GT all use the exact same G92 core just at varying frequencies.

The 8800GTS and 98GTX are both clocked higher than the GX2.

So 2 x GTS/GTX are going to be faster than the GX2, and 2 x GT's just slower.

Doesnt quite work like that, the newer drivers for the GX2 helped it along, it can depend though on specifics.

And, the point where you said, ''8800GTS, 9800GTX, 9800GX2, 8800GT all use the exact same G92 core just at varying frequencies'', isnt stricly right either. E.g, the 8800GT has 112 SP, where as the 8800GTS/9800GTX have 128SP, which makes a difference, never mind the 50mhz clock difference.

It depends on what your going to do with the computer .

If you want solid frames in games , get the GTS cards in sli and be done with it but if your looking for scores and want the fastest thing you can buy ide go for the gx2 in sli

If your running a single card setup then get the gx2 and clock it up .

Im running the gts in sli and its fast enough to play any game out right now at above normal frame rates .
 
9800GTX and 9800GX2's are a waste of time and money. There are much cheaper cards available that will play any game at 1920x1080 without issues.

If you want to play recent games at this res with AA it will not matter whether you have an 8800GTS, 9800GTX (single or SLI), or GX2 - the 512MB of ram will limit you at these settings far more than GPU power will.

Just buy an 8800GTS or 3870x2 and be happy until 1GB boards or the true gen arrive.

I didn't think I'd have to point out the GT's lower shader count any more as it is such common knowledge now.

The clock difference I alrady mentioned, and I also said they'd be slower than the GX2.

Also the latest 174.74 drivers boost the GTS and GT just as much as the GX2.
 
SLi 8800GTS



"What's interesting is the fact that the GeForce 9800 GX2 is slightly faster than a pair of GeForce 8800 GTS 512MB cards right across the board—even despite the 50MHz core and 125MHz shader clock speed deficits. We knew that the GeForce 8800 GTS 512MB was memory bandwidth limited, but a 30MHz increase in memory speed shouldn't be all that it takes to alleviate that problem. We're not alone seeing this though, so it looks like the BR04-300 chip is working its magic in one way or another".

"Again, we see another impressive showing from the GeForce 9800 GX2 – it manages to eke out a 10 percent performance advantage over the GeForce 8800 GTS 512MB SLI configuration at both 1920x1200 2xAA 16xAF and 2560x1600 0xAA 16xAF with all of the in-game details turned up to the 'Very High' preset".

"Not only that, but it's also considerably faster than the GeForce 8800 GTS 512MB SLI configuration again. Nvidia hasn't really been specific on the performance advancements made between the GeForce 9800 GX2 and the GeForce 8800 GTS 512MB SLI configurations, but I can't quite believe that an almost 30 percent performance differential can be made up with a driver drop—at least not in a game that's been out for a relatively long time".

SLi 9800GTX



G80 & G92

 
Only reason to buy the 9800 GTX is, if youyr going to buy 3x of them and TRi SLi them, if youyr only going to get 2x and SLi them, then you may as well the 9800 GTX's that are £100+ cheaper, saving £200+ on the same cards.

I wouldn't get the 9800 GX2 either now seen as its only got a 2 months life-span, as theres a single 9900 GTX coming in July thats gona whoop it, so either wait till then if you can, but if you can't then get 2x 8800 GTS 512mb's in SLi, as they cheap as chip now, and will be the same as having a GX2, just your GX2 will be 2x seperate cards, and be £60+ cheaper. :)

SLI gives redundancy as well. Should one GPU or memory chip on your 9800GX2 fail your 6uggered. If one goes on SLI you can just send the faulty card away for replacement and run at 2/3 of the speed with the remaining card. SLI wins on price and piece of mind:D - so long as your mobo can handle SLI.

Thanks, (one thing 9800gtx sli 1600x1200 at 48 fps and at 1920x1200 49 fps ??? )

looking that that make's me think that 9800gtx in sli is a really fantastic deal

Its not though, as they are just 8800 GTS 512mb's that are slightly clocked higher, and had an extra £100+ slapped on em, you may as well buy 2x 8800 GTS 512mb's to go in SLi, exact same cards, but will be £200+ cheaper, buying the same 2x cards at over £200 extra is sheer lunacy.
