PCIe lane limitations

[GissumGreve]

hi guys, thanks to Linus' video on two of the new haswell-e CPUs I noticed that the CPU I've already bought for my coming build (Intel Core i7-4790k) has a maximum # of PCIe Lanes is 16. As I've been wondering whether to get a GTX 970 in SLI or a single GTX 980 I was guessing I would go with the 970's, but will this CPU be a bottleneck due to lack of PCIe lanes? Is this a factor? Should I go with the single 980?

Limited pcie lanes are not that big of a factor with 2 970´s

Edit: But if you are using more than 4 nvidia quadros it could be a factor to consider to upgrade....... ftw quadro gaming

Simple answer: No.

 

Slightly longer answer: There have been plenty of tests done on this topic, and none of them have shown any sort of noticeable difference in real-world tasks (like gaming).
