I am planning on buying a new SSD and Graphics Card(s) to finalize my current gaming rig. But, I'm having some difficulty deciding between what card(s) to get.
Here is my current rig:
AsRock Z68 Extreme4 Gen3 Mobo
Intel Core i7 2600K (stock speeds)
16GB DDR3 1600MHz RAM
2TB Sata HDD
2x XFX 6790 CrossFire
The choice of cards was due to my purchasing all the computer parts at once in store (Micro Center), where there wasn't much option at the time.
Since I've been an AMD/ATI person in my years, I decided to switch over to nVidia to see how things were doing there.
I'm looking to finally get triple monitor gaming underway at good rates (at least 50-60 fps) on high/highest settings. Currently, I use two monitors for windowed games (LoL, Minecraft, etc) and web browsing, and single full screen for the more important games (BF3, Dead Space 3, Guild Wars, Crysis, Witcher)
I'm looking to future proof my computer for at least a few years, so I'm not too concerned on spending some money now. Of course, money is limited, so I am looking to spend a max of probably $2000 for the cards. The 690 sli would probably not work unless I spent more on a new PSU.
Edit: The reason I was looking into the Titan / Titan SLI was due to the 6GB of memory.
Well the GTX 680 is able of running a triple monitor config. If you feel you want to take an extra step further, then 680 in SLI will give a bit more performance than the 690. On the other hand though there are many things to take into consideration prior your final choice. Read these threads for further info:
I would say that with multi monitor support that AMD has the stronger solution. If you don't care about 3D, you don't really do any 3D rendering/editing, or you don't play with physx turned on in games then I would go with something like a 7970 or 7970 ghz edition card.
Future proofing does not exist and its very hard to predict where things will go however getting the higher end cards normally insures that over time your card will still obtain value and will still be a strong performer. If you were going to go with a 3 monitor setup I would stick with AMD eyefinity. Because none of the games you listed you play use the feature set that Nvidia has with the exception of nvidia surround 4 displays and 3D.
