I have read so many reviews and there are so many conflicting ideas on which to pick regarding AMD and NVidia that when it comes to two GPU's it is mind bottling (lol).

The plan: run games at highest specs on my 2560 x1440p monitor. The two main contenders are the Radeon 7970 and the GTX 670. Now the waters get a bit muddied when talking about custom coolers, different brands, warranties, etc, because they all matter but performance comes first. I MAY watercool in the coming future but for now I am undecided (if I get the Corsair 800d as I plan to then watercooling will absolutely happen.)

The games I play are Crysis 3, Diablo 3, Mass Effect 3, Dead Space 3, Dragon Age 1 and 2, Guild Wars 2, Battlefield 3, Star Wars The Old Republic, and the big one I play most is World Of Warcraft.

Now I want to point out first that I had 7970's crossfired in my old system and Mists of Pandaria actually ate the two cards up with the game dropping to as low as 34 fps at points. That is INSANE for two of the big dog cards. I see lots of reviews say how great they are supposed to be in WoW but it just didn't really play that way (could have been mobo but not sure).

I am also pretty sure I will have to run multi GPU to push this big of resolution at max settings so I am prepared for the costs associated. Also, call it ridiculous, but I have built a pretty solid X79 system and would like everything to match my blue/purple, white, and black color scheme if possible.

OK so here are the options:

1) USED but in perfect shape Evga GTX 690 for $800. Has the 2GB per card of ram and the green lighting on the "GEFORCE GTX" actually correlates with the Motherboards green LED's.

2) New EVGA GTX 670 (the stock model and cooler) at $319 per card so the SLI setup cost would be $638. These are the 2GB models and are at stock clocks. The white on the cooler looks nice as well with the rest of the system.

3) New XFX 7970 Black Edition w/DD cooler at $385 or for crossfire setup is $770. These are overclocked from factory and are the standard 3GB memory. These have the red strip in the top are which does not match but I could hopefully find something to cover up the red. *****I have these in the box still and wanted some information before I order something else if its needed*****

Now I'm not opposed to even a different suggestion but these seem to be the best options I have run across. The reason I chose the XFX for the 7970 is because the cooler is actually of good quality and the card/cooler doesn't look cheap as hell. I am not wanting something to last 8 years but also now 3 moths so Ill just buy new hardware when I need it if this outfit becomes sub-par to my expectations.

Any help would be spectacular and thanks in advance!

*****System Specs*****
MB-Intel DX79SI
CPU-Intel Core I7 3820 3.6ghz but will be at 4.5ghz
CPU Cooler- Cooler Master Hyper 212 Evo
RAM-Corsair Vengeance 8GB DDR1600
PSU-Corsair HX-850
SSD-OCZ 120GB
HDD-WD Caviar Black 1.5TB
Corsair 600T White case.

7970 Crossfire...but not the XFX model.

Edit : Didn't see the price between CF 7970 and 670 SLI, though. If that's the case, then I think 7950 Crossfire is the best option you can choose.

Get a single 7970 OC or GHZ edition and you are set for two years at least

If its between 7970s for $770 and 670s for $638 I'd say go for the 670s. Really though, you'd probably be better going for 7950s. They are about the same performance as 670s, but they are slightly cheaper and have 3gb vram like the 7970s. Plus with an OC they can easily hit stock 7970 clocks and only be 2-5% slower. I think that 7950s are the most cost effective option and you will be future proof for AT LEAST 2-3 years.

670 ftws are nice, a little more expensive but better quality. Crysis 3 will really only be the game that puts the two cards to any real use. Maybe wow also, I have read that in highly populated cities that the cards get a good workout. But the other games are easily maxable on a single card setup pretty much. At 1080p on sli 670 ftws playing crysis 3 at the absolute max settings resulted in very playable frame rates on the first level. Sure I got knocked down quite a bit during the rope physics moments, but I have heard that is a problem for everyone. I'm sure I could lower a couple settings while not missing out on anything visually, but I just did the first level real fast as a baseline. Game crashed at second level so I'm waiting on the patch to finish downloading, then I can see how the rest of the games fares as I have heard that the first level tends to be the most demanding on gpus.

They are roughly 10-12% slower than a 7970, but with a solid OC they can meet or beat stock 7970 performance. The real appeal is the cost. You could Tri-fire 7950s for pretty much the cost of two 7970s.

Check out this Sapphire. It has the boost clock, and it's on sale for $290. You'd have a hard time beating Tri-7950s for $870.

Now I keep hearing about how bad 3 or more GPU's scale so wouldn't 7950's in Tri-fire be a worse setup than 7970's in crossfire?

Also cant the 7970 overclock to then have a larger advantage in the end?

If its really not all that different I guess I don't really see the point of the 7970 if the 7950 is practically the same gpu, but hey I'm all for a big price savings.

I see no one is too hot on the GTX 690 option. I figured it might be that way.

Actually a 7950 is 2-5 % slower than a 7970 clock to clock. So your best deal is to grab 2 or more 7950. The scaling is good on tri-fire if you know how to setup your system

Not sure how thats possible when it has like 12% less stream processors

Well a 7950 cant clock high enough. If you get 1200 you are really lucky. Basically 7950 is a low binned 7970. I would choose 7950.7970 if you care about top performance

12% less stream doesnt mean that is 12% slower. If you have a 1000 mhz 7970 a 1075-1100 7950 will match it

Yes I can afford It, but spending less for the same performance is a great option. I already ordered and now have two of the XFX 7970 BE DD's sitting here right next to me that I haven't opened because I wanted to get some opinions before I put them in my system.

Of course you could OC the 7970s faster, but at some point diminishing return comes in. Like for most setups two 7950s will give you plenty of power even without OC. Now if we are comparing three 7950s to two 7970s, it's no contest. If the 7950s had less memory or a narrower memory bus than the 7970s I would think differently, but if you are spending 850-900, and your mobo is capable, it wouldn't make much sense to do two 7970s over three 7950s.
