Hey all,
i have a bit of a dilemma on my hands regarding the bandwidth of the PCIe. My goal is to upgrade my system to a 3way-SLI using GTX 480s.
Everyone knows, that for a 2way-SLI, its best to insert the cards into 2 x PCIe 2.0 x16 supporting x16/x16 configuration. However, when u move up to a 3way-SLI setup u have a couple of options depending on your mobo: PCIe 2.0 x16 supporting x16/x16/x4 ; x16/x8/x8 ; (and the best of them all) x16/x16/x16 configurations
The question is: How much will the performance of the 3way-SLI GTX 480s be affected by anything less than PCIe 2.0 x16 supporting x16/x16/x16 configuration.
Im asking this because i was looking forward to upgrading my mobo to the RAMPAGE III EXTREME but then i noticed that its configuration of the PCIe 2.0 x16 is x16/x8/x8 for the 3way-SLI setup! I know that this mobo is a "technological masterpiece" due to its OCing capabilities and not only, but im more focused on the GPU performing best rather than the CPU if it would come down to a decision between the two. My other option would be the ASUS P6T6 WS Revolution witch supports "true" PCIe 2.0 x16 in a x16/x16/x16 configuration.
Im looking forward to all your opinions on the mater,
THX!
