Two GTX 570's or one GTX 580?


May 12, 2011
I'm building a new pc this Christmas and I wanted to know what would be more beneficial. I am either gonna get two GTX 570's for SLI or one GTX 580. I might eventually grab another GTX 580 to run in SLI if I go that path, but it would take another year probably before I would drop the cash on it. With the specs I have below of my new pc would I have any problems running any of the new games coming out like Rage, or Skyrim on high settings with just one 580? And if so would the two 570's in SLI mode be better? Sorry for the noob question, I am only somewhat knowledgeable in computers. Just want some opinions of what others would do, thanks.

New pc specs:
Intel I7 Quad-core 2600k 3.4GHz
Patriot Gamer 2 Series 16GB DDR3 1333 memory
1000W power supply
With the components you listed I would get two GTX 580's , but if it takes another year for you to get the other 580 then it would be up to you if you wanted to wait. The 580 is a powerful card and you would be able to run any of the games coming out at high settings. Two 570's are better than one 580 but two 580's will beat all comers. You had said it would take another year to get the other 580 but that could change and it could take less if you waited for the other 580 then you would have a top performing Pc acle to max out any game for quite some time.
What is your motherboard ?

Both setups are overkill for most games out now. You should be able to max out most games no prob with two 570's and one 580 will be enough for anything you throw at it in the next 3 months. I would go with two 570's because it is simply more effective than one 580 and you will extend the card lives. If you put all the stress on one 580 the card will have a shorter lifespan.
On a side note: DO NOT I REPEAT DO NOT buy these video cards anytime before Christmas. The next gen video cards are going to be out soon and on those cards the higher end ones will be twice maybe even 3 times more powerful han one 580. the next gen cards wil prob be out by the time you buy this system. Dont waste 600$ now when you can spend 600 and get 3 times the performance later.
Neither....let's see why .... but XMas is a long time away in PC terms so all bets are off every 30 days. Newer cards will drive down the price of current cards and will offer a moderate increase over last year's comparable cards.... for example, to give ya an idea, the 560 is 30% faster than the 460 "outta the box" but only 10% when set to the same clock speeds.

Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:

$ 205.00 560 Ti - 900 Mhz (495/862) $ 0.41 - $ 0.48
$ 230.00 Asus 560 Ti - 900 Mhz (495/862) $ 0.46 - $ 0.53
$ 320.00 570 (524/873) $ 0.61 - $ 0.73
$ 480.00 580 (616/953) $ 0.78 - $ 1.01

Twin 560 Ti's factory OC'd to 900 Mhz gets you a larger cooler and various other design improvements that make it easily able to be OC'd even more. I listed the Asus model separately since it's $25 more but I am comfy w/ these as I have successfuly OC'd every one (8) I have had to 1000Mhz .... only one of them req'd a slight voltage bump and none ran over 82C in SLI. By comparison the 570 is not that great an OC'er and if ya do a yahoo / google search you will see that many users fried their boards pushing the voltage beyond manufacturer's spec.

But here's the deal .....

the twin 580's costs more than twice as much as the 560's for just a 10% performance increase.
the twin 570's costs 40% more than the 560's for just a 1% performance increase.

Om a side note.....

-the 2600k offers miniscule gains over the 2500k
-16Gb offers miniscule gains over 8GB
-1600Mhz worth it over 1333MHz

1000 watt PSU for twin 580s
850 watt PSU for twin 570's
750 watt PSU for twin 560's

Tho if OC'ing I'm a helluva lot more comfy with the 850 watter for the twin OC'd 560's and a 2500k/2600k at 4.6 - 4.8 Ghz

Your timing is problematical.
There will be new28nm graphics cards out 1Q-2012, along with the 22nm ivy bridge cpu's.
They look to be able to give you stronger performance, at mostly the same prices as we see now.
If you buy in December, you will be at risk of buyer's remorse.

Today, a 2500K , a GTX580 are about as good as it gets.
Yes, sli of lesser cards show good benchmark results, but how good do you really need to be for good gameplay?
Odds are, you will be very happy with such a system.

IN 2012, you can always sell the cpu chip and the GTX580, to replace them with the latest and greatest.
