What is the difference between TH2G and an SLI setup?
Not the same purpose at all.
- SLI is "two cards working as one" for additional
performance. That's all. If I'm not mistaken you can only use 2 displays when using SLI (i.e only the main card's outputs).
- Having two graphics cards with SLI
disabled allows you to use all 4 outputs. So you can use 4 displays for desktop apps, or run SoftTH (which requires 1 ouput per display) for multi-mon gaming.
- TH2G doesn't care if you use SLI or not, and will allow you to connect a triple-screen setup to one output only.
Now for the performance part. I used SLI'ed GTX260s in 5040 and they're totally up to the task with "moderately high" settings in recent games. AA has quite an impact on nvidia cards at such high resolutions though.
Take a look at the nav bar on the left : the
TripleHead FAQ covers pretty much everything you should know before you make the jump. Then search your faved titles in the
Games list and take a look at their Detailed Report, it should give you an idea of how common native TripleHead support is and how hard it is to make it work otherwise.
Hope this first reply helps a bit, and welcome to the WSGF !
