SLI or Crossfire?? pls help!!

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

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.

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.

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?

okey..so should i go for two 8800gt in sli or just ONE 8800gts ??? Which is better performance wise??

With the choices you give, if you must purchace now, the 8800GT SLI setup will give you the best performance.

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.

No problem.
Glad I could assist you!

Only 6 more days
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.

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.

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.)

no news over at AMD yet.

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.

it even perform better then the 3870X2 with no filter.and with filters on it will be even better.

maybe this is better
