LOL Vodka and water.

Vodka 7-up with a shot of coffee, that's how I drink my Vodka, Stoli is my choice.


Just seems like that post came out of no where.

You clearly don't know what you're talking about.

I have 1.5GB 480s and I'm limited to 1xAA in 5760x1080 3D Surround, reaching VRAM limits in many games (such as Metro, Just Cause 2 and others).

You said 3D surround. Yeah, you def need more frame buffer for 3D.
I was talking about non 3D gaming for that. CallsignVega said he even hits 2.7GB in some non 3D games, so I doubt you could play in 3D with 3x 30" monitors even with the 3GB cards.

Anyone have Tri-Fire 6950s unlocked to 6970s and OC'd benchmarks? Single 6950 TFIII review: http://hothardware.com/Reviews/MSI-R...eview/?page=12

There will be no higher res than 1920x1080 in 3D on a single screen until there's a move from DVI/HDMI 1.4 as the bandwidth supports maximum of 2 x 1080, 2560x1600 x 2 is too much for these so I would say 3GB is a fair sweetspot for high res & multi monitor users.

Interesting how much ATI's drivers for Crossfire have improved.

Oh yeah. What did you mean when you said 5760x1080 3D then? The review I saw had no problems with 4xAA in any of the games and even did 8xAA in HAWX 2 with 1280MB frame buffer.


Oh and for the "special" kid that tends to foam of the mouth when talking about things he doesn't know:
Alien Vs. Predator:
1-way = 63.9fps = 100%
2-way = 120.2fps = 88%
3-way = 169.5fps = 77%
4-way = 208.1fps = 60%

A video showing a fixed benchmark that only loads small data assets is not proof of anything.

In real situations the engine that powers AVP would load an awful lot more data assets into VRAM then this LIMITED fixed benchmark does. Thus apply more stress to the cards reducing the performance and even possibly scaling.

Look at my 2 sig rigs. I have run benchmarks and I play a lot of games on both of them and I can tell you this for a fact: 2 6970's are not beating 2 570's as bad as they show in some of those reviews. That is plain lies. From my experience they are almost identical most of the time.

If you read my post, I said:
"There will be no higher res than 1920x1080 in 3D on a single screen"

5760x1080 is 3 screens, each still has the limits due to the reasons I've mentioned.

Frame buffer usage is game dependant, some will use less, some more - seems though more advanced graphics in the game = more usage (which hurts in the game I play like JC2 or Metro)

I also believe that quad SLI is not very practical.
Yes, you get better benchmark results with 4 and yes you get a little better performance in few games, but not in most.

Here are some benchmarks where 4-way scaling is not that good as in your example.

Guru 3D comparison

Obviously it's not 4x580 vs 3x580 - 590 is slower than 580 but still, 2048 cores @ 612mhz in theory should be much better than 1536 @772mhz and it's not.

By the way, it would be really good to see benchmarks of 2,3,4 SLI in 1.5GB and 3GB in multi monitor resolutions (2D and 3D) by some review site...

Where are you getting those numbers?

Because 120 to 169 is not 77% and 169 to 208 is not 60%
