GTX 470 tri-SLI good idea?

post #1 of 7
Thread Starter 
I am looking at maybe running triple-monitor sometime. I do not wish to dive into liquid cooling though to cool the cards. Will it be alright to run them on air? I have excellent airflow in my case. Also what PSU (brand, wattage and well priced. Must be good but not too expensive) do you recommend? I am also thinking of moving to a six-core (probably 970) eventually. Thanks guys.

1000W would cut it close when overclocking and the future upgrade to a six-core I suggest at least a 1200W unit. 3 way 470s pull close to 800W at full load from what I read.

SILVERSTONE ST1200, Antec AX1200, and the Corsair AX1200 are good 1200W units.

Agree with above water cooling would be only way IMO since the cards would be so close would get very warm even stock clock/volts. Will the 922 even fit triple dual slot cards?

Tri GTX470's do well in 2D Surround with most games on 3 monitors. I had to change to SLI performance mode (1 monitor @ 1080p) in the heavy games like Metro and Crysis for good frame rates.

Loud they are, but that depends on what you are used to. They were the reason I went to water cooling (Maybe I'm just a wuss ).

You will also have to upgrade your Power Supply to 1000w or higher. There is no way your current one will handle 3x 470's.

GTX570's are quieter and run cooler. You might just save up until you can afford 3 cards, the price may be lower by then.

as long as you can handle the noise from the fans (good sound and headphones) it should do well. I had 470's before the 570's and it was a major drop in noise levels.

The main problem is noise/heat. Even with a great airflow case, you'll still see high temps. Tri-SLI 470's run 2D surround very well in most games, aside from the killers (Crysis/Metro).

As for the PSU, I believe you can get away with a solid 1000w, but for some head room a 1200w would be better (just incase any volting/oc'ing down the road).

I prefer the Corsair series AX1000, or AX1200. But silverstone and Antec are also just as good.
