The crazy world of SLI & Price/Performance - Page 2

post #11 of 12
-Microstutter sucks.
-SLI/CF solutions would require a larger PSU than the single GPU solutions. And a larger power bill.
-There is no guarantee SLI/CF will even be supported in all games/programs. And if it is supported, your scaling value will vary.

Needless to say, I think there's good reason for the price differential. Single GPU solutions are just plain better regardless of their raw speed.

All of your points are valid - but I feel they are apt for a single display with 1920x1200 resolution or smaller.

Unfortunately, when you start hitting 2560x1600 and above, things are not so apparent anymore. For those unfortunate enough to notice micro-stuttering at high resolutions, they either have to deal with it, or put up with the decrease in performance as even current generation single GPU cards (though are better than previous gens) are going to struggle here.

Regarding SLI/CF profiles and support, I used to feel the same way about it too until I found programs like RadeonPro and nHancer, which allow users to create custom profiles until AMD or Nvidia roll out their official game profiles. And even then, those programs allow further customization for those profiles according to his or her own personal preferences.

Nowadays, there are very few big name titles that do not have SLI/CF support, either right out of the box, or end up getting support added soon after. Lesser known games (especially Indie titles) that generally don't get this kind of support typically don't need it anyway as a single card is likely to be more than capable on its own. Yes, I am generalizing, but I really cannot recall a game just browsing through my own Steam library where SLI/CF is not supported. Scaling is certainly debatable, but flat out zero support is hard to find.

And to your point about the cost of electricity and a larger PSU - I feel that if someone is going to take the time to really invest in one or more large monitors and drive them with high end GPU's, not only would they most likely be aware of what they are getting into, but they probably don't have an issue with money either. If people are struggling to live off of ramen noodles and can barely pay rent and utilities, then their priorities are misaligned. Regardless of the fact, even with such drastic sacrifice in extreme cases, I'm sure they definitely know what they are getting into at that point.

I understand the smoothness, and lack of hassle when dealing with a single GPU and a single monitor. Lately, I've found how much of a pain it is to hack some older games to make it work in Surround, but sadly, that is the state of affairs when you fall into a niche market segment. The upside to this is that once the effort is put in to make it work (which really isn't that hard anyway), it pays itself off when you immerse yourself into the game.
