Hi, I'm planing to build an gaming computer that can last me for 2+ years. I will be using 1680x1050 res. I was wondering should i get an 9800Gx2 or 2x 9800 GtX sli. Will there be better performance?

2x9800gtx sli will deliver higher performance. But since a 9800gtx only perform slightly better than a g92 8800gts, you can get 2x g92 8800gts sli for almost as good performance for around $200 less.

This model comes with factory overclocking plus a free game. As it is, it's still slightly slower than 2x 9800gtx, but faster than one 9800gx2.

And spend the extra $200 on a quad core cpu... which will be useful in 2+ years.

98GX2 will be overkill for that resolution I believe.

You could do a few things, get the 2 9800GTX's and hope they last 2 years,

get one 9800GX2 now and if you can, get another later, or lastly get a

9800gtx or cheaper and get one of the next series graphics card when it

comes out. It all depends on what you feel like doing as far as upgrades

go. You definately won't even need a 9800GTX to run games for at least

another 6 months (excluding crysis)

well im going to go with the 2x 9800 Gtx and after the 2 years ill go with an laptop :D 
April 23, 2008 2:07:55 AM

the 9800 GX2 can be overclocked to 9800 GTX Frequencies. the 9800 GX2 is basically 2 down clocked 9800 GTXs :)

You should seriously consider what I said about 9800gtx and 8800gts. Look at this:
http://en.expreview.com/2008/04/03/geforce-9800gtx-revi...

And for 8800gts's g92 core, 675mhz (as tested) is only slight oc. The factory oc in the card I linked is 678mhz. My 8800gts is oced from stock 650mhz to 780mhz, fully stable with no heat problems on stock cooler.

You are spending more money for less performance.
April 23, 2008 2:26:06 AM

yes but remember the 8800 GTS 512 doesn't have a tri-sli future:)  lol but yes its true they are basically the same card:p

Thanks dagger i was going to lose about 150 dollars thanks.

The 98GTX is the top solo performer therefore would be the one to go with in a 3-way and not two SLI setup. 9800GX2 is just 2 88GTX utilizing 1GB of VRAM instead of 768 you are given in an SLI setup. I think that the 9800GTX is obviously designed for tri-sli market and therefore cancels out the 512 GTS.

Those are for people on the bleeding edge, and will cost you... a lot. Besides, with the 9900 coming soon, it's a dubious deal even for the bleeding edge.

the 9800 GX2 is just 2 9800 GTXs down clocked:)  I'll say it again:D  haha

It's more like 2 g92 8800gts downclocked. :na: 
April 23, 2008 3:48:14 AM

you can also say that. Its the same, they run on the EXACT same video card board. I oced my 9800 GX2 to match the 9800 GTXs:)  soo I'm happy:D 
April 23, 2008 9:07:39 AM

I rather get a single GX2, SLI two 9800 GTX's seems to be more waste of electricity. Who cares if you get an extra 5 FPS, thats not even worth it.
April 23, 2008 11:46:03 AM

yea plus you have the quad sli available. Its obvious that the 9800 GTx in SLI outperformed the 9800 GX2 because the clocks are different.

Look at this chart:



Oc the 9800 GX2 easily to 9800 GTX standards:)

Quad sli? In one year a single gpu card would likely match your sli solution. Those things move way too fast for sli/crossfire to make sense. :p 
April 23, 2008 1:42:23 PM

You can't always be sure of that. I mean look at the new 9800 GTX. It doesn't match 2 Ultras or w.e. So we don't know if the new cards will do that. the only 1 that came close to match 2 Ultras is the 9800 GX2.

Either way we will have to wait.

And how much do 2 ultras cost? And when did it first came out anyway? I'm pretty sure it's less than a year ago.

I have two 9800GTX's in SLI and I am pretty impressed (going from 2 8800GTS 640mb in SLI). I overclocked them to 766/1915/1125. I have the fans at 80% (veryloud) but they both idle around 38C. Haven;t done much testing, but am able to play Crysis in DX9 ( (with the shaders, texture, physics, and pp on very high hack - love the God rays!) at 1920x1200. First Contact, the early less graphics intensive level of the game, I get 35-40 FPS average, which is fantastic. The later, more graphics intensive level where everything is frozen over and crazy alien robots are chasing you, I get about 25fps average - still quite playable. COD4 all maxed out in DX9 at 1920x1200 and I am getting well over 120FPS average. Think I'm set for a good while.
April 24, 2008 2:00:26 AM

yup no1 said they weren't good cards :)  I just didn't feel like waiting for 2 9800 GTX so I got the GX2 and oced it to GTX amounts:)

Is there a big difference in OC when getting a cheap Club 3D GTX compared to for example a EVGA at stock speed?
What did you buy scooterLibby?
I just want them to survive untill the G200...
April 24, 2008 1:21:45 PM

EVGA has a lifetime warranty and a step-up program. They'll also honor their warranty if you overclock the card or change the cooler.

Frankly, I went EVGA and hope the G200 arrives in time to take advantage of the step-up program. Even if it doesn't, bah, it'll push the price of the 9800GTX down enough to SLI them.

No. there's no difference. You're paying more for brand name and lifetime warranty.

I chose EVGA for some of the reasons other people mentioned: Step Up Program (not voided by overclocking!), Warranty, Customer Service. As also mentioned, there is little if any technical differences between the brands. There are some exceptions like Palit, though, who add their own cooling systems. I ordered my EVGA's from from Newegg and there was a $30 drop in between the first and second...I should have waited.
April 24, 2008 4:33:30 PM

The GX2 would be less of a pain in the azz to fit though. I had to move one of the fan/hard drive bays an inch farther than the rest of the bays on the front to be able to fit two GTX's. Looks kind of weird but oh well. Also make sure you have a PSU with 4 good 6 pin PCI-E connectors if you go GTX.

MSI also add much needed dual slot coolers to their 8800gt and 9600gts models. Their OC model of g92 8800gts also comes with factory volt modding, but only stock cooler. The 8800gts stock cooler is good though.
