Yep, won't be running 3 way SLI on older Nvidia chipsets/775 or AMD cpus any more. 🙂3 way sli is crap for the gtx580?
Cpu bottleneck?
Drivers?
Not very good scaling there.
I like the way they did there power consumtion figures. No furmark crap.
[FONT=verdana,geneva]See, one GeForce GTX 580 is already a power-house in terms of performance, with two cards we already started noticing CPU-limitation in certain titles, e.g. the two GPUs would like to go faster yet the processor (an overclocked Core i7 965 @ 3.8 GHz) is, with somewhat dated titles, not able to keep up with the GPUs 100%.[/FONT]
[FONT=verdana,geneva]With GPU performance nearly doubling up each two years this is going to become a problem in the years to come. See, a lot of games these days do have multi-threaded processor support, yet often that is limited to two or three CPU cores. The processor industry is making a huge shift to multi-core processing and with the serial architecture of the processor it poses an issue for multiple and high performance GPUs gaming wise.[/FONT]
[FONT=verdana,geneva]In short, we really need faster per core processors to deal with that issue, unfortunately processor manufacturers are only focused on more cores.[/FONT]
GTX 580 3-way is stupid overkill.
