motherboard damaged near gpu

[myth77]

i have asus board that somebody damaged really hard with srewdriver near the gtx g960m gpu (the motherboard has two gpu cards)...Some lines/nets on the motherboard were cut very deep and long and some just on surface...For three longer cuts i made wire jumpers and solder everything...but for several others shorter cuts that (maybe only half milimeter) i applied solder only to fill the gap (i used no wire)...Now the board starts i get the picture..but whenever i tried to change to 960m gtx it starts very slowly..sometimes even black screen...
So i am wondering is there a difference between a wire jumper and a solder only jumper for a smaller gaps between two lines on board? or there is something else i missed while trying to solder everything back?

Re: motherboard damaged near gpu

Photos would be useful. Solder vs wire wouldn't be a problem, bridged traces is more likely.

There may be damage to internal layers though, if the scratches are deep enough
