Quick question.. 
New to building PC
 
Been running fine with 9900k Aorus Master Z390 EVGA 2080TI FTW3 3600 CL16 Memory
How important is it to have the GPU connected by two seperate PCIE connectors?
Currently I have 2 cables from PSU to GPU. They both have 2 connecters per cable. one end from PSU the other end has two 8/6 connecters per cable; 2 cables from PSU to graphics card total.
 
Would I see any benefit using a traditional 8/6 cable with only 1 connector on each end?
Ive seen some stuttering at times playing Witcher 3 not sure if this is power delivery issue
 

Copy that, I ziptied the extension cable and I'm using the "main" end.
As of yesterday I downloaded afterburner, Not OC the card, just set the fan speed to 100% (previously was Precision with 100 mhz core nothing to ram freq) Still troubleshooting the stutter
Haven't ran any benchmarks at all. 
Running 3440x1440 res, Wolfenstein runs fine, seems to only be witcher 3 in high population cities while running. \
 
Ill check things out with GPUz
