Buy another 470, or two 460's?

[Psy-Blade]

Hey guys,

I'm itching for an upgrade and I'm thinking its about time to go SLI.

I'm just stuck between getting another GTX 470 OR getting those MSI 460's.

I'm worried about heat and noise with 2 470's, that's the main reason I am considering the 460's.

What do you guys think?

Maybe 5850 xfire would b better. Im pretty certain it would. If you want to stick with nvidia i would add another 470 because i dont think it will be worth selling amd losing money with 460s. What psu do u have. 700+ would be perfect. As for heat you could get an after market cooler. I wiuld recommend arctic cooling or zalman but you might have space issues. What case do u have?
