NVIDIA's GeForce 6 SLI: Demolishing Performance Barriers

Half Life 2: AT_coast_05
In our at_coast_05 benchmark we see a fairly similar situation, with all of the GPUs being CPU bound at resolutions below 1600 x 1200. At 1600 x 1200 the 6600GT begins to drop off, but toss on a second card and it delivers performance slightly faster than that of a single 6800 Ultra.
With AA/AF enabled, the 6600GT actually does a lot better in our second demo, using SLI it manages to offer performance equal to that of a single 6800GT. The 6800GT and Ultra don’t need SLI too badly, even with AA/AF enabled, in this demo, only at 1600 x 1200 with AA/AF enabled does the 6800GT see a real performance gain from SLI.

BUYER BEWARE!!first, I have this ASUS motherboard and two GigaByte 6600GT's. AFter countless hours of trying to get this to work AND of course upgrading bios and drivers, I came to find out that these two gigabyte cards are not certified by Nvidia and they will not work in the sli mode on this ASUS board. ASUS has not returned my calls or my emails, but gigabyte, bless their hearts, wrote me back and said in essence: "our 6600GT cards work on OUR board" so too bad. Thank God for Newegg and their awesome return policy. I am returning these two and getting one 6800 GT, but of course, not from Gigabyte!

It would be nice to see tests at 2048x1536. After all if you can afford the videocards for SLI I bet you can get a proper monitor as well ;)Denial - Thursday, December 2, 2004 - link
Again, why no vanilla 6800's? How would they compete with the 6600GT's in SLI? This is starting to get rediculous.nserra - Friday, November 26, 2004 - link

#69 Yeah i agree.But let me tell you i already see something that SLI will give me.
Having a 6600 and a X700 on the same PC.

I don't know if anyone's said this, but SLI is an absolutely stupid idea, why on earth don't they take the 3Dfx Voodoo5 approach and just stick two GPUs on one card? Surely this would yield similar benefits without special mobo requirements.. 16x PCIe is easily enough bandwidth to cope... then just double the amount of RAM on the card and surely this is more viable solution? sure it'd be an insanely costly card, but still cheaper than an SLI setup, and lets face it, once a single card can outpace your shiny new SLI setup, that SLI setup is going to look poor value for money and you're just going to waste both cards, it seems obscene.stance - Thursday, November 25, 2004 - link
will the new duel core amd cpus that come out mext year be supported by this motherboardstance - Thursday, November 25, 2004 - link

ANAND, please answer:1.) Can you really force SLI for games with no profile in the driver?
2.) please make 2048x1536 or higher Tests (my CRT can da 2304x1440 :D)
3.) please make 8xAA Tests
4.) please check if HDR (high dynamic range rendering) in far cry works in SLI mode (other sites say no)
Especially # 1.) is very important.
If only games with a profile can run in SLI mode, SLI will not become very popular imo. We know nvidia- they will only have profiles for benchmarks and most common hyped games. For not so popular games there surely will be no profiles...
thx
