dual vs triple SLi

[jpk]

I currently have a SLi setup with my EVGA GTX260's. I'm thinking about adding a third matching 260 since my board will support it and adding another 260 would be relatively inexpensive. Will there be an adavantage of doing this or am I just upping my BS factor? I really want to make my machine a little future proof for a couple of years. Thanks

I'd wait for the gtx 460 to come out (6 weeks ) and sell both gtx 260's and buy 2 gtx 460's.
I don't think the gtx 200 series plays with triple sli nicley.

Yes, this. I think you'd be better served by moving from the 260's to newer tech instead of adding another 260.

What will the cost be for the 460's?

Don't listen to these guys. I will have an evga gtx260 for sale when my 5870 gets here on Monday. 😉

I'm running GTX 280's in tri-sli and definitely see the difference vs. the dual GTX 280 SLI set up I had previously (found a third one cheap when they were being discontinued in favor of the GTX 285). I should also note that I am running at 2560x1600 where the tri-sli really pays off. If you run a lower resolution, it is likely overkill.

For the incremental cost of adding another GTX 260 (~$200) you would likely see performance similar to a dual 470 sli setup, minus the DX 11 support (which is not yet widespread anyway) and save $500 in the process.

I'm planning to keep my 280 tri-sli setup until the next round of GPU's - perhaps GTX 485(?) if they bump the performance and deal with the heat/power issues. There is not enough performance difference to justify upgrading (unless I went to tri-sli 400 series which would be insanely expensive).
