Tech Hounds uploaded the second part of their article. Well, looks like SLI is worth
the money, just not for the (promise of) performance.
Last week, we took a quick look at what NVIDIA's SLI has to offer. In that
article, we concluded that while SLI does work, you should not expect
tremendous gains in frame rates. In average, SLI can only offer around 30 %
increase, occurring mostly when AA and AF are enabled. However, performance
is not the only feature of SLI. In addition to multi rendering, SLI can be
used in SLI antialiasing mode. In this mode, the two graphics cards will
perform antialiasing with slightly different sample patterns and then
combine the results.. Read on over here.
