470 GTX 3 SLI is it worth it? - Page 2

Read this 3-way SLI GTX470 review. The limitation mentioned of the CPU would not apply to your situation as you are running a much larger resolution than the tested 1920x1200/2560x1600. I would expect a noticeable gain in framerate when going from 2-way to 3-way.

However, 2 areas need your attention:
a. Power
You will need a more powerful PSU than your current 850W. I would go with either the Corsair AX-1200 or Antec's HCP 1200. At least, 1000W should be used.

b. Heat
This will probably be easily solved if you put the 3rd GTX470 into the loop. Even if not watercooled, putting the 3rd on the last slot of your UD-3R mobo should also work out.
thank you so much
I was looking for some benchmark test like this

You are welcome.

Here is one more review of GTX470 3-way SLI. Unfortunately, the highest resolution tested was 1920x1200.
Their conclusion is more or less in line with that of Guru3d (CPU limitation, power and heat).

As long as you have proper cooling for tri-sli, and have enough resolution to run it, its an awesome thing to have. You can check out the reviews and benches of tri 470's and they scale in a linear fashion, the only time youll see an increase as low as 30% is when your running at a low resolution which then shows that your running into a CPU wall.

I love my tri-sli, its awesome for triple monitor setup, and it even made a difference in Metro 2033 at 1920x1200 (was then able to max EVERYTHING out) Just my 2 cents from a tri-sli owner

For what you have I would definitely get the three 470s. However can your motherboard properly support it? I don't know much about that gigabyte.

Worth it? Yes. May take some experimenting with drivers/video cable set up/settings.
Aftermarket (preferably water) cooling will be of the utmost importance...expect a decent fps increase depending on the application (game) Not every game wil benefit from it.

Looking at your setup, it looks like your running on air... heres a question to you and anyone else on tri-sli air... How the hell do you keep this running cool? And isn't the noise at this point insane?

I have the twin frozr coolers and the noise is okay but not the best. I used to have one reference cooler for a 470 and that drove me insane as a single card. Plus my dual twin frozr is dumping so much heat into the case that the top card is roasting on a 800Mhz overclock.

I would love to consider a tri-sli for nvidia surround and I just wonder how you guys are able to manage this. (I have 8 fans running in my case already)

I used to have my 470's on air also, when i would play games i had to turn the volume up on my speakers
thats why i decided to watercool my CPU and GPU's
I used to hit 85c at 95% fan speed
now my temps on water is about 50c full load


here is how my set up looks like

im gonna change my PSU and add a 3rd 470 and waterblocks if i decide to do it.

water is the safest/most silent method...even with 2 cards, I found their noise easily surpassing the sound of my case fans.
