Question 1

I currently have a 600W power supply in my PC. Will this be enough to run this card?

Accepted Answer

Use the power supply wattage calculator on the power supplies home page that newegg has provided. Depending on your specific build, will determine how much power you will need. 
I chose this video card because it needs less power than most others in its class. I also went with multiple ssd's to lighten the load on my build.

Question 2

Can it run 4k games smoothly? Has anyone crossfired this card and how much better is it crossfired?

Accepted Answer

It will smoothly run most of the common games at 4k like Dota 2, League of Legends, TF2, Ect but if you get into more demanding titles you would have to either lower the resolution or turn the settings down.

Question 3

My MB is PCI-e 2.0. This card is 3.0. Will there be a problem using this card on my MB?

Accepted Answer

I'm using it on my PCI Express x16 1.0 (not 1.1!) 8 year old motherboard just fine. Just hope you're not using Vista as they don't release drivers for that OS anymore.
