2 BFG 7800GT's are faster than 1 512MB GTX!

I knew there was I reason I picked up a second card! It goes in tonight. I'm looking forward to testing benches.

HardOCP really vindicates SLI because they test actual game performance rather than just benches.

There are a couple of areas the 512 is better but for sheer FPS, dual 7800GT's rule.

Yeah they sure are better, just think about that. 2 7800GTs should be the strength of (I know this isnt exact but bear with me):

2x20 Pipes = 40 Pipelines
2x256 Ram = 512 Ram

Also, two cards means two sets of speeds. Its almost like running dual channel with videocards, just with more pipes. Real world performance isnt as strong as stated above, but its not too far away.

I would expect it to, as it's kind of like having 2 6800's in SLI, they are faster together in SLI then a single 6800Ultra...

But also, the 780GT is no slow card, and it's the 512mb's younger brother, so I would not expect the 512 to be twice as fast as a single 7800GT

I agree. I'm a big fan of Tom's as well. However, when you start talking SLI benefits on this site, there are certain "members" that are very much in the opinion that benches aren't real world testing etc.

Incidently ram doesn't add together in SLI.

Don't forget that in "current" SLi setups, one card is only running at 8x, not 16x.

So 2x7800GT would be giving 30 pipelines at 24x, not 40 pipes at 32x.

You need an ASUS A8N32-SLI board (or anyone coming out after that which offers dual 16x pcie) to get the "full" benefit of 16x2 PCIe. Which is why I bought it in this new setup.

But that's not to say that reg SLi PCIe isn't fast.... it's damn fast.

No wonder the Asus performed better, it's the equivilent of 4 7800GTs...

And the BFGs performed better because they were set to "High", while the 512 GTX was set to Ultra.

Your mixing bandwidth with hardware.
Current pci-e runs both cards at 8x OR both cards at 16x (with the 32x boards),
Running 2 cards in sli does give you double the hardware strength...just not double the bandwidth on most motherboards.
It Would be 40 pipes at 16x or 40 pipes at 32x depending on the mb.

The review I linked indicated that they use the Asus A8N32-SLI for testing of cards. HardOCP was one of the main reasons I bought the A8N32 board, knowing I intended to go continue SLI.
