Counterstrike: Source VST Performance
With Half Life 2 less than a month away, performance under the Source VST is very important.
At 1024 x 768 the performance is already pretty impressive, but with SLI it is skyrocketed into a completely new level with the 6800GT showing a 23.8% increase in performance and the 6600GT going up by around 54%.
It's impressive to see that at 1024 x 768 with 4X AA the 6800GTs in SLI mode are still CPU limited by the fastest AMD chip on the planet.
At 1280 x 1024 we see something quite unusual, the 6800GT gains much more from SLI than the 6600GT. The 6800GT received a 63.5% performance boost from SLI while the 6600GT gets "only" a 45.7% improvement; given the beta nature of the drivers we'll avoid hypothesizing about why.
At 1600 x 1200 the performance gains peak just under 70%.

Thanks bob661! Anyone have any info on AGP x700's? If ATI gets them out first, they get my money... :-)HardwareD00d - Friday, October 29, 2004 - link
Those benchmarks are amazing! I wasn't going to shell out the dough for SLI, but now I'm going to reconsider.I was glad to read that the 2 PCIe slots being only 8x will not really be a performance issue. A lot of people are down on nForce4 because it won't do 2 16x slots. F***ing A nVidia Nice JOB! Now if only NF4 had soundstorm...

See http://www.theinquirer.net/?article=19340 for 6600GT AGP availability.KraftyOne - Friday, October 29, 2004 - link
Yes, this is all fine and great, but when will the x700 and/or 6600GT be available for AGP ports for those of us who can't afford all the latest and greatest?HardwareD00d - Friday, October 29, 2004 - link
I have only two words to say:Anand Rules!

On page one it says the SLI slots are electrically x8 slots instead of x16. That is not correct, they are x8 data slots, but will still provide the full x16 electrical power needed to the graphics card.

What PSU were you using for these tests?suave3747 - Friday, October 29, 2004 - link
I would expect that a 6800 Ultra Extreme SLI setup will not be outdone by a new nVidia card until at least a year from now. And at that time, when you bought the second one, it would push you from mid-range back towards the top for much less than that new card would be at the time.This is brilliant by nVidia, because:
A. It allows you a way to buy half of the GPU setup that you want now, and half later. That's a great plan for a budget-oriented consumer. It will make GPU purchases a lot easier for parents to swallow on holidays. It allows for someone to give them $1200 for a ridiculously powerful GPU setup.
B. It will keep their high end cards of today selling well all the way into next year. The way the market is now, people want a new-gen card. They don't want a 5950 right now, they'd rather buy a 6600. This will keep 6800 series and 6600 GTs selling all the way through 2005.

2 Video cards - No thanks.Price factor,heat factor,noise factor,space factor,extra & new technology factor(guinea pig)
No thanks to this avenue.
I feel sorry for the poor saps who buy into this crap and spend $800+ alone for 2 x 6800GT's only to be outperformed in a year by a newer generation single card setup.
I highly doubt this will ever become a trend.If you think so,then ask how many people have dual CPU systems.

Hmm lets see, I can get a 6800 GT for less than two 6600GTs, and the 6800GT is faster..... Let me think about this, no SLI for me! MAYBE if you want a mid-range card now, then get the 6600GT and upgrade when another 6600GT is very cheap and have the equivalent of low-end card then?. I still think it's worth dropping the extra cash on the 6800 GT. But I guess when it cam time to upgrade, I could just add another 6800 GT? I kinda doubt it.
