6970 (or 6950 unlocked) crossfire too much for 1920x1080?

post #1 of 7
Thread Starter 
Plan on building a new rig with an i5-2500k. Was wondering if 6970(or 6950 unlocked to 6970) cfx is too much for a 1920x1080. Trying to future proof this setup for at least 2 years. Also what kind of PSU would I be looking at for 2 cards like this? I was thinking of a 1000W PSU. If overclocked, they won't go any higher than what CCC allows.

1) 1 6950(Unlocked) is good for 1080p, but you'll need another if you want to max some of the newer games coming out (Or Metro 2033).

2) 800W at the max, and even then, that's overboard.

No reason not to, some games need that little extra muscle to get smooth at high settings. And you could easily run two of them on what you currently have, even overclocked (assuming someone with BFG knowledge chimes in and lets us know if this unit is capable of putting out it's rated wattage and amperage).

cfx 6950 is the way to go now, i heard Sapphire 6950 Dirt 3 Edition have a pre-unlocked bios by just switching bios on the card.

Well supposedly according to newegg and what not this PSU puts out a steady 800W. Guess it's actually able to do higher than what the box says? But the reason for a new psu is that I'm giving this rig to my father and I want to go for a modular psu since this one isn't. And according to newegg psu calculator two 6970 require 932 where 2 6950 require about 803.

I at least want to be able to power 2 cards that way if the 79xx cards come out and are infact better I can upgrade to those and not worry bout a psu since they supposedly wont need as much power due to architecture designs

Not true.

I own 2 of them in Crossfire.

The switch is backup BIOS. Even then, I've heard its a hit and miss deal :/

Newegg's Power Calculator is as useless as it can ever be. Two 6950's can EASILY run on sub-800. If your looking for modular, Seasonic and Corsair have 650-750w units, which are 100% modular and 80+ Gold. They will (should) be able to power two current generation cards with no problem at all.

No idea about the 7XXX series. Nobody knows if they will use less or more power. But I speculate, even if you go with a 750w, you'll be able to power two of them just fine.
