GeForce GTX 590 in SLI -- four GPUs -- heck how do we justify that? Well, it's cool, funny and lovely to play around with but there's no way we can rationalize 1200 EUR for four GPUs to play some games on. As you have seen, scaling with four of the most high-end GPUs available is a difficult and daunting task.
Now one card with two GPUs, if properly supported scales extraordinary well. With 4 GPUs setup in SLI mode things simply get increasingly difficult, we often see with multi-GPU setups. In some games the performance of four GPUs is magnificent, in others 4-way multi GPU mode just does not kick in, and then in other scaling becomes an issue whether or not that is driver or CPU limitation related.
Good examples here where COD MWF2 and Anno 1404 where performance was actually lower than one card, hey it happens often with these two titles that GPU starts to blow after two GPUs. No biggy as the framerates remain exceptionally good.
Where the 4 GPUs did kick in, they kicked in well though. But you need to be at very high monitor resolutions, have extreme amounts of CPU horsepower and a fairly spicy power supply. Our system peaked to a power draw of roughly 900 Watt at one point -- which is a new record all by itself really. I am not so sure if we need to be proud of that though. Four way GPUs in SLI also meant much more noise pressure, as such we reached 44 dBa with the four GPUs stressed, slightly high but that's still quite acceptable.
go on buy them 4 580s brah
get that negative performance ye
flex that big dick you got
yet look at that tri
