The fourth slot saw a 6% reduction in performance compared to the first.
The third PCIe slot was down 13% on performance compared to the first.
Again, we see similar margins in Tomb Raider as we did when testing with Hitman.
The Asrock Z97X Killer works well with three-way setups as does the Gigabyte Z97X-SOC Force.
The Z97X-SOC Force takes a slight hit on the fourth PCIe slot, dropping a few frames per second.
The BioShock Infinite results are interesting.
The Asrock Z97 Extreme6 provided maximum performance on slots one and two while the third was 15% slower.
This slot was 28% slower than the first and second, obviously a significant reduction.
