660ti 2gb SLi vs 670 2gb SLi vs 680 4gb

Since I haven't bought any parts yet, what are the actual SLi advantages vs a single card? My computer will be built for gaming and some editing/3D modeling here and there but mostly gaming. Looking to run anything i throw at it and have every game 60+ fps with everything maxed, and i mean everything. Trying to benchmark it to be able to handle crysis 2 and bf3 60ish without dropping frames too much. Since my current screen isn't 120ghz can someone also recommend a good gaming one that has great quality preferably under $220. I WILL NOT BE OVERCLOCKING.

Heard that one can overheat easily, does anyone know of a better one or band that would be better to get?

Also does anyone know if I will need a GPU with 2 fans on it for my uses?

  1. Now, before people start shouting about SLI and how you should never do it, let me say this:
    I had a GTX 680 but found that although I could max everything out pretty well at 1080p, some games such as BF3 & BM: AC would often not stay above even 60FPS, never mind 120FPS for a 120Hz monitor.

    Therefore, I reckon one would need to go dual-GPU if wanting 120fps min in every game completely maxed out. I would recommend 2 GTX 670s from that list. Don't bother with the 660 Tis since the memory bus will cripple them.

    Having said all that, (everyone knows) multi-GPUs can have a lot of problems but if you're willing to go for it (which I did, see my sig, and I think it's awesome) then do.
  2. I prefer single card solutions over dual. For a single monitor gaming that is plenty and I would only consider a SLI setup for multi monitor extended resolution. Dual fan coolers are usually better if you are considering overclock but the single fan ones are fine at std clocks.

    And I prefer a dual card setup over a single card rig, more horsepower and I always have a back up card if one fails.
