GTX 770 Bottleneck

Solution


This is incorrect. Some motherboards have a PLX chip, which is like a switch for PCI-E, this allows 3 way sli using a 16 lane CPU.

For example:

AMD 4-Way CrossFireX™ and NVIDIA® 4-Way SLI™ supported by PLX PEX 8747 Bridge

It shouldnt bottleneck butt 3 way sli is kind of waste. there comes so much studering and only a litle performance compared ti 2 way.

Aldo check your mobo does it support 3 way sli

Yes my mobo supported 3 way sli.
i have got 2 way sli system now, but i dont like it's performance especially new games.So i want to buy a new gtx 770.
Should i buy new gtx 770?
Or Should i wait for 4-5 mounths and buy a new graphic card ?

Honestly, I would sell the gtx 770s, get a gtx 1070 or 1080.

Its also the same kind of chip they use on dual GPU cards, so they share the one pci-e slot.
