Which gives the best performance, Two Geforce 9600 GT in SLI or Two 3870 in Crossfire, or Two Geforce 8800GTS in SLI??? and why??

More about : sli crossfire pls

the 8800gts is 320 MB whereas the 9600gt and the 3870 are 512mb...

The ammount of memory is not the only important thing. The GTS comes in 3 flavors. The older G80 based cards have either 320Mb or 640Mb and are, speed wise, placed in between the 9600GT/3870 and the G92 based 8800GT. The 8800GTS 512Mb is also based on the G92 chip and is nearly equal to the older 8800GTX/ULTRA.

The 3870 and 9600GT are verry close in performance. The 3870 will normally win with AA and AF dissabled where as the 9600GT will win with the filters enabled.

As the 8800GTS 512 is one of the top cards currently out, an sli setup using it will be, by far, the fastest. It should easialy match and probably surpass the 9800GX2 (which is 2 of the GTS 512's underclocked on a single card).

A 9600GT SLI or 3870 CrossFire configuration should be faster than a single 8800GTS 512.

thanks outlw6669..................so just between the 9600gt sli and 3870 crossfire, which would be the better performer...

They should perform similarly. Scaling with the 9600GT is excellent as is the 3870's scaling. What dose your current Mb support? I think that would be the deciding factor. If it is an Intel based Mb, it will support CrossFire and you should get 2x 3870's. If it is a nVidia based Mb, it supports SLI and you should get 2x 9600GT's. In either case, it may be prudent to wait a week or two until ATI and nVidia release their new generation cards.

Why not just get ONE powerful card like the 8800GTS 512? less fuss dude.
And not all games support SLI/crossfire...

once again, thanks outlw6669!!!! I am planning to assemble a pc, so i am planning to get my mobo based on the graphics cards...I have noticed that the 9600gt is gddr3 but the 3870 has a gddr4, does it make any difference?

Not really. GDDR3 has lower latency and GDDR4 has higher bandwidth.
I would tend to agree with romulus47plus1 that a single card will probably be more than enough for you.
I would also like to reiterate that ATI and nVidia will be releasing their cards within the next 2 weeks (17th for nVidia and 23rd for ATI). It is probably worth the wait at this point. Worst case, the price of all current cards should drop a bit.
June 11, 2008 11:55:26 AM

okey..so should i go for two 8800gt in sli or just ONE 8800gts ??? Which is better performance wise??
June 11, 2008 11:58:14 AM

I agree with the single card as well.

I was originally going to say pick which one complements your wallet, but you have two competitively priced cards right there. I think you will end up with a good solution no matter how you go about it.

With the choices you give, if you must purchace now, the 8800GT SLI setup will give you the best performance.
June 11, 2008 12:08:16 PM

okey, so two 8800gt sli gives better performance than one 8800gts 640mb rite???

A single 8800GT 512 will edge out a win over a single 8800GTS 640. The GT, along with the GTS 512 are based on the newer G92 chip and are faster than the older GTS 640/320 cards.
So, yes. 8800GT 512 SLI will be faster than one GTS 640.

outlw6669, you were GREAT....thanks alot....most probably i'll wait for the new cards from nvida and ati like you said.....thanks alot!

Nothing wrong with considering a single 8800GTS G92.

But SLI 8800GT or even 9600GT will more often than not dominate any single GPU. There are few games SLI is broken in. The 8800GTS 512MB is powerful enough to handle most games cranked, but SLI 9600GT does have the potential to blow it out in gpu intensive games/levels.

Have a look at these charts vs 8800GTX and 8800U:

8800GTS 512MB one vs two cards.

Crysis Vista very high isn't very kind to single GPU's: The 9800GX2 does well, (but SLI 9600GT would probably be only 27-29 fps range though)

We shall see how the upcoming single GPU's handle crysis very high. Hopefully with better performance than the 9800GX2 even.

Only 6 more days :pt1cable: 
If Fudzilla is acurate, a single GTX 280 should be enough to handle Crysis at 19x12.
Gods I can't wait to get my hands on one of these.

thanks pauldh, it was also very informative!!

I "upgraded" from 8800GTS 640mb to 9600GT in SLI and only got about a 20% boost in benchmarks which translated to basically nothing in games.

outlw669 from which of the 12 colonies do you hail from?
June 11, 2008 1:56:01 PM

9600GT SLI will beat 9800GTX across benchmarks.i have read many review it says 9600GT SLI shows the best ability of SLI.and 3870CF is also the best of CF as well.other card from either side dont bring many benefit in terms of fps. i would get a pair of 9600GT and OC them and SLI will bring best scalable performance to your eyes.3870 dont OC as well as 9600GT.but its your call.

if possible we really stick to single card solution... for mother earth...hehehe less energy needed

Nothing in games? Sounds like you either play cpu limited games/settings, or didn't tweak your games to take advantage of the added GPU power. Crank the eye candy, explore GPU demanding game levels, then see what you get. I see 80+ % scaling in some of my actual games between single and dual 8800GT. I find "benchmarks" to scale worse (3dmark06, crysis gpu bench no fsaa, etc.)

Yeah, it will be fun to see for sure.

Funny they don't specify the detail levels, only resolution. Medium, High, Very high Vista DX10? What are we talking?

1920x1200 all high better happen (as well as the GX2 does now). 1920x1200 DX10 very high I doubt is going to happen on any single GPU in 2008. If it does, I know my two G92's would be 4-sale! ;) 

Then add 4xaa at 19x12 DX10 very high, will we even see it in 2009 on a single GPU?

25x16 talks for dual GTX 280 would be incredible if very high DX10. Gonna need 1GB vram for that. Check out the 9800GX2 getting 4 fps at those settings, no fsaa either. :lol:

okey, fine....so which sli configuration should i take, two 9600gt or two 8800gt????

Oh God you're so indecisive...
I mean, enough talk here already you should know which to choose already

Okay, if you can wait for 30 responses and still not make a decision, then I recommend you waiting a week or two for newer cards.
Then prices will drop and you'll have a truck load of choices then, be it SLI/crossfire or single card solution.
Have a nice day chap.
