Good and bad news. Bad news is, when I went to order my 2nd GTX 480, they charged me for a third. Good news? I'm getting my 2nd and third 480's by the end of this week! biggrin.gif

The other thing is, now I have to get a better PSU in order to do 3-way sli. And It might be a few days too a week before I can get that. I'm going to be selling my HX850w to get something better like:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817171055

I'm just hoping it fits in my Phantom case. It looks a bit bigger than your stand atx psu.


My LAST question is this: Would I be able to put all three cards in my system, but only run two in SLI, the other sitting there with PhysX turned off?

Thanks guys and let me know - Jessekin32.

I plan to. I WAS going to get an h100 and do that, but the OC and h100 will have to wait since Getting both of those cards frown.gif

I might have to make a new thread for this question, but does anyone know how well my 480 3-way SLI setup will work for Nvidia surround for BF3? On a single card, with one 1080p monitor, I get about 41-60 fps on all ultra, Vsync, no motion blur. I'm thinking that if I do surround, then I'll have to lower some settings.

worse case scenario is that you will just have to turn down AA.

You may be able to run 3 on the 850. I would suggest getting a kill-a-watt power meter. $15.

If you run the 480's at stock speeds with voltage at 1v, you should be pulling around 850W or less gaming. Furmark will pull 150+W more (no point in doing so anyways). But you should get a 1000W+ if you want to do any overclocking at all.

Thank you both of you. I'm glad so many people here are willing to help me answer my questions. It's been a while since i've been with the community, but I'm glad to see it's still so alive and kind.

I'm probably going to open up a new thread in the intel forums about some OC questions, since last I OC'd was back in 2010, and was working with an AMD 965. Bit different now, but I know the basics still.

I agree with above if the meters are that cheap. I use my meter that monitors the whole house to give me a rough estimate.
