Choosing which gtx590/6990 model to buy

[ps3hacker12]

hi my company is allowing me a free purchase of any graphics card currently out there to allow me to render faster.

although im pretty happy with current render times i decided to go for a gtx 590/6990 and keep it for my gaming PC if its too powerful for my liking or too noisy ill just sell it on ebay

anyways my current PSU (also bought off my company) is this Antec 1200W trupower PSU:

although i have been using a lower wattage PSU until now to avoid wasting energy.

here are my choices:
power coulor 6990:

remember i p-lan on SLIing two of these card, although i will definetely be selling the second card off straight off because i really dont need that kind of power!

my current setup:
i5-2500K (OCed to 4.8Ghz with arctic freezer pro 13 co cooler)
a Gigabyte GA-Z68XP-UD4 mobo
4gb 1600Mhz ram
an antec DF-30 case
windows 7 64bit
i think thats most of it!
oh and my current graphics card setup is SLI gts 450s (performance is ok i geuss but lacking in some games)

i am currently gaming on 2 1080p monitors but am likely to go to two 32" 1600p monitors (on the company too).

thanks looking foward to your advice!

first off i should mention that power supplies waste the least power when they are running at about 50% max load. above 50% is still pretty effecient. but under 25% they always do very bad.

why game on two monitors? puts your crosshair/character split between screens. 3 is the way to go. and with that in mind the radeon is the way to go. need two nvidia cards to do triple monitor gaming. but i also perfer the 6990s performance to the 590.

for which card is the best its really down to warranties and reviews for me. i would rather have zero problems than 1% more performance. and i really dont like spending 10 hours on the phone for an rma number.

it would have to be beetween 2 1600 monitors or 3 1080p monitors which one would you choose? (32" 1600 x 2 vs 27" 1080p x 3)

so what PSU should i be using?

 

[amputate]

Last I checked all the 6990 cards so far have the exact same specs so that won't matter much. (I'm using a sapphire one)

a 750W PSU SHOULD be enough but you might want to add another card in the future so I really don't see a reason to not use your 1200w o.o

And imo, I would have gone for 3x 1080p instead of 2x 1600 just my opinion.

 

[DarkSidesHero]

Recommended specs for the 6990:

750w for a single 6990.
1000w for crossfire.
1200w for crossfire for optimal performance.

Can't wait to get my 6990 soon

sop the general consensus is the 6990, ive heard that the 6990 is loud though any truth to that? (and apparantly runs hotter).

[EDIT]: vs the gtx 590 that is.
