both 2 way and 3 way sli comparing 16x16 or 8x8 is literally no difference at all, even for 3way sli it results in 1-2 fps is test that are achiving over 150+. Only 500+ tests of this with the highest end gpus so the only reason for the 5930k is 4way sli or 3 way sli and you have components that use more then 4 pci lanes which is very uncommon for most users.

Hello see comment top (new to board so it should have appeared here)

My motherboard is a Gigabyte GA-X99-UD4P with 4 x16 slots for GPUs With 40 PCI lane CPU all 4 are useable x16, x16 for 2 GPU x16, x16, x8 for 3 GPU x8, x8, x16, x8 for 4 GPU For 28 PCI lane only 3 max useable x16, x8 for 2 GPU x8, x8, x8 for 3 GPU So for 2 or more GPU better performance. If only one GPU then save money with 5820. Gigabyte site gives 3 or 4 GPU PCI setups shown in diagrams for 5960, 5930

Do you think it gives that much better in performance for sli? The price difference is about 200 dollars now.

John Sanderson (07:29 PM, July 28, 2015)

From the review it looks like the 5930 vs 5820 have similar performance but 5930 is 100 GBP more expensive. Main difference, that may justify 5930's price (and made it my choice) is number of PCIe lanes supported (40 vs 28).
