The Cowboys improved to 6-1 after a 31-21 victory against the Giants. Romo completed 17 of 23 passes for 279 yards, three touchdowns and one interception.
Although Romo has had more impressive stat lines during his career, Jones said it was one of the best performances of his time in Dallas.
"I'd have to say that may be [the] best game I've ever seen Tony Romo play," owner and general manager Jerry Jones said. "That was an outstanding game. He was pinpointing the ball, making the kind of plays and protecting the ball."
Wide receiver Dez Bryant was a big part of Romo's success against the Giants, finishing with nine catches for 151 yards, including 136 yards in the second half. Bryant said changing his cleats and putting on a visor led to the big second half, while Romo said it was a result of better focus.
"I think he wanted a couple of plays back in the first half and he mentally locked in," Romo said, apparently unaware of what a visor and different cleats mean to Bryant. "He played an outstanding game. He was tough to handle in the second half."
Cowboys running back DeMarco Murray had 128 yards and set an NFL record by surpassing 100 rushing yards in seven straight games to open the season. Murray leads the NFL with 913 rushing yards and seven touchdowns.
Dallas is second in the league in total yards after finishing 16th last season.
The Cowboys play hosts to the Washington Redskins next Monday night.
