Which PSU - 2x AMD 6990?

[psylence1]

How high a PSU for 2xAMD 6990, i5 2500k, 8gig 1600mhz ram, Gigabyte GA-P67X-UD3, 240gig sata 3 ssd, antec 900 case

1000W will be fine, but i'd take around 1200W

Um, why do you have a dual 6990 with a i5? You talking quad Crossfire....

Any of these would do it (Make sure that they have at least four 8-pin connectors):

Would reccomend the Corsair, EVGA, or OCZ ones...

... Or Antec/XFX/Seasonic...

Which cpu would you recommend other than i5? thanks

 

[shrkbay]

yeah, i was also wondering why i5, why not Xeon or i7, but probably 2500k beats all i7s till 950 and 2600k. this i5 is great, it beats all AMD's current CPUs and OCs great.

I'm just curious what sort of resolution OP is trying to push to figure he needs CF 6990s lol. I wouldn't be surprised if it's 1080p...

As for CPU, I'm sure the 2500k will keep up just fine but at the point of spending $1500 for graphics cards, just spend the extra $80 or whatever on the 2600k... seriously.

omfg 2x6990 ? :faint:

 

[plznote]

Yeah, are you doing 3-monitors?
No need to invest boatloads of cash.
Give it to the plznote charity for one.

Im only getting one 6990 for now and was going to buy the otherone maybe in 2-3 yrs when higher req games come out. Wanted to make sure I have enough PSU for then. Monitor is 27" ultrasharp dell 2,560x1,440

^WASTE IMO! Get a GTX 580, much quieter, cooler and great performance, also when SLIed will be better than a single 6990

I think it beats all quads and hexa, when talking about games, from the previous generation of i7.



Besides the problems of dual gpu setup the 6990 would be somewhere like gtx580 sli in terms of performance.
You should ask for opinions from people that own a 6990. Also above 1080p 2 Gb of RAM per gpu is a plus.

From all the gaming benchmarks ive seen the 2600k would only provide 2% or so better performance than the 2500k when both overclocked. Wont be using many apps where the 2600k looks to have a better advantage.

@ionut9, hm, i'd say 6990 is more like 570 SLI with a lot more memory
