6970 Crossfire matches 580SLI for $680, while unlocked 6950s dip as low as $550 for about the same performance.

As for the Mobo, choose the one that looks good, X8 is'nt a big problem, but if you go with the Raedons, you might want to get the WS REVOLUTION for tri-fire.

I am looking at a similar system, I like the ASUS P8P67 PRO LGA 1155 personally alot of posative reviews on newegg and good reviews on youtube. Only question is how many monitors do you have in your setup and what is t he resolution?

Also when you list your monitors and their resolutions what are you using the computer for? The 2600k is complete overkill for gaming where as you can save $100ish and go with the i2500k

Obviously price is not a concern to kasket.

Yes from the looks of it, I too have an unlimited budget for my rig but SLI'd 580's is complete overkill on one monitor no matter what the res. As well as the 2600k being a complete non factor in games over a 2500k.

probably is, or he would've gone with a 590s and a 990X.

I'd Rather stick with Nvidia as far as what I do.

My normal use for this will be video (HD blu-ray) and photo (15megs avg per pic) (I use CS5 Master Suite) and blu-ray burning. I also am a WoW player and a few other PC games

my Monitors are not decided yet. I had some thoughts but not final. I will probably make my decision in the next week with 1 for now and 2 more before years end.

Thoughts in that direction are welcome also.
April 10, 2011 7:40:37 PM

yeah, my budget for the system is almost at it's limit
April 10, 2011 8:37:35 PM

Yeah with that monitor I hate to say it but 2x580's are extreme overkill atm, You would be better off going with a 2x570 setup or even a single 580 for now with the option to upgrade later. 1 580 gtx will run WoW at over 120 fps, and every game out at over 30 ......with everything turned on and all the way up. With 3d at that res 2x580s would still be overkill. You could even get a 590 gtx for now to hold you over and it be $300 cheaper than SLI'd 580's.

However since you will be using it for photoshop with 15mg pics def keep the 2600k, it will outperform the 2500k in photoshop areas.

The monitor is not set in stone, but this is all good info. I still need to pick the MB

Asus WS Revolution for twin 580's in SLI at x16 x16 .... only MoBos w/ NF200 are gonna give ya that. most do x8 x8. read the review here .... not only does it beat the Gigabyte UD7 in every bench bit check out thePower and Temperature page:

http://www.tweaktown.com/reviews/3795/asus_p8p67_ws_rev...

Now if ya wanna do twin SLI at x16 x16 plus a dedicated PhysX card at x8, the the Asus Maximus IV Extreme is your baby.

WARNING: Be very careful w/ cooler selection. In most full tower cases, even:

Corsair H50/H70 , Antec Kuhler 620 will hit GFX Card in Slot No 1
Thermalright Silver Arrow won't fit in normal orientation, must rotate 90 degrees

I just finished a build w/ two factory OC'd 560 Ti's (900 MHz). As soon as I get CPU OC dialed in, will try for 1000 MHz whoich seems like everyone before me has been able to do.

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:

6850 (371/634) $0.42 - $0.49
6950 (479/751) $0.51 - $0.65
6950 Frozr OC (484/759) $0.59 - $0.75
560 Ti (455/792) $0.53 - $0.61
6970 (526/825) $0.64 - $0.81
560 Ti - 900 Mhz (495/862) $0.43 - $0.50
570 (524/873) $0.64 - $0.77
580 (616/953) $0.81 - $1.05
6990 (762/903) $0.95 - $1.61
590 (881/982) $0.79 - $1.4I

In Metro 2033 (1920 x 1200):

twin 580's do 65 fps
twin 570's do 54 fps
twin 900Mhz 560's do 49 fps
twin 560's do 45 fps

I'd love to see how three 560 Ti's do in tri SLI against twin 580's.

With what your spending, the CAS 9 memory seems mismatched. I see lotta posts saying memory CAS don't matter but few published results. Here's one:

http://www.anandtech.com/show/2792/12

22.3 % (SLI) increase in minimum frame rated w/ C6 instead of C8 in Far Cry 2
18% (single card) / 5% (SLI) increase in minimum frame rated w/ C6 instead of C8 in Sawn of war
15% (single card) / 5% (SLI) increase in minimum frame rated w/ C6 instead of C8 in World in Conflict

For $45 or so, or roughly a 2.5% increase in system costs, if ya can improve your SLI performance by 5%, I say go for it.

BR - If ya need to play BR but only burn DVD's, I have 3 of these Plextor 320SA's.... oldest is October 2009 ... no issues yet.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Otherwise, this Asus Model comes with 5 BR burnable media

With CS5, you'll wanna know about this site if doing movie editing (CUDA unlock instructions)

Great monitor but for the Photo work, you're really gonna want a IPS monitor. The defacto "entry point has been the Dell U2410

http://www.amazon.com/Dell-UltraSharp-U2410-Performance...

But I have seen that Asus has a new IPS panel out but the price seems too good to eb true

If the GeForce GTX 560 Ti were able to support 3-way SLI there would already be benchmarks out there that could be used for comparison.

Wow All good info and I am reading and searching some in between typing.
