So guys what's the deal with SLI how well does it work on the new NVIDIA cards? Dual card setups used to be absolutely plagued with problems. Do most games support SLI these days or are they few & far between. The reason I ask is I've been told a dual card setup is practically a minimum requirement for running games on a single hi-res monitor (2560x1600/1440) is this true & is there anything else I should be aware of when building a dual GPU system?
 
SLI tends to have less problems than crossfire from what you tend to read on forums, but that's not to say that it is issue-less... mostly tends to be when a new game comes out that drivers or a patch are needed to fix those issues, which Nvidia are usually pretty good at but game developers are sometimes lackadaisical about

all the most popular games support SLI (or do so after aforementioned driver update and patch)

I have dabbled with SLI and it didn't cause me any issues in the games that I tried it on

a 7970 is currently borderline at that resolution in a couple of the more demanding games, so you'd have to guess that it has virtually no futureproof-ness

it depends on your budget as to what cards you go for to pair up, if you absolultely possitively have to run everything on "max" settings at that resolution then you need to be looking quite close to the top of the tree

with kepler cards apparently due to start trickling out in the next month or so, now would be a bad time to be buying NV cards
 
I've used SLI since the last 6 series and not had any issues with it. 95% of it is user idiocy. It's a matter of installing the drivers and clicking on the enable SLI radio button. Anything worth playing usually has a profile at launch and the odd thing that doesn't you can either create a custom one and if that won't work you can use the SLI-AA options to ramp up the aa levels. It's hassle free for the most part.
 
Thanks guys your input is appreciated I do intend to wait till the new cards come out till I go buy anything just trying to get a bit of heads up on what the current situation. I'm not one of these people who insist on having everything Maxed out to the max on ultra, I don't mind dropping things a little but not too much as I do like my eye candy & I'd imagine at 2560x1600 it tastes even sweeter.
