there is something so wrong with new system build I've done downing games is slow I mean really slow I been over 12 hours and only got 1.3 gigs of a 22 gig game I have tried reinstalling the killer drivers and nothing has help I really don't want to buy a network card to fix this is there anything I can do or try thanks.

ya tried the ones from EVGA and from Killers site DLing games from steam its jumping all over the place from sky high to 0 bytes its so bad it has taken over a day to download a 22 gig game something that wouldn't take more then 15 minutes with my old P55 classy MB I think I'm going t o try and get a network card if that doesn't fix it looks like I'll be getting a refund an go with another MB brand that does have killer network stuff on it.

no not OC anything running a stock i7 8086k  update I got it working had to uninstall everything.

its working perfectly now after uninstalling all of the drivers I got from EVGA web site and installed the ones from the cd that came with the Motherboard.
