"This is the biggest win of the year for us, no question about it," Gordon said.
Gordon, who stayed among the leaders but never led until he passed Burton on the outside in turns three and four at Richmond International Raceway, outran Dale Earnhardt to the finish, winning by .744 seconds.
"I knew we had to take advantage of Jeff on the restart," said Gordon, who won for the third time this year in his Chevrolet. "Whichever way he went, I was going to go the other way."
Earnhardt, racing for a $1 million "No Bull" bonus, moved into second place in the points race on a tough night for points leader Bobby Labonte and defending champion Dale Jarrett, who had been in second place.
Jarrett slammed into the wall less than halfway through the race, lost 14 laps during a green-flag stop for repairs and finished 31st.
Labonte, another of the five drivers racing for the bonus, seemed in position to make a run for the money after emerging from the pits in second place with 45 laps to go. But on his first lap back on the track under the caution, smoke billowed from his power steering mechanism, causing him to pit twice more and dropping him out of contention.
Labonte, a season-worst 26th here in the fall, finished 15th.
With nine races to go, Labonte is 158 points ahead of Earnhardt, who is seeking his record eighth Winston Cup championship. Jarrett is 164 back.
"We're going to be dogging it and doing all we can," Earnhardt said.
Gordon was excited about his battle with Burton, something almost to be expected at Richmond.
"He always races me hard," Gordon said. "We've had some great battles here at Richmond."
Burton beat him a thrilling side-by-side battle in the race in 1998, and both hve been in the top five in four of the last five fall races at Richmond.
"We didn't always lead but we didn't give up," Gordon said. "We had great pit stops that kept us in contention."
Until the end, neither Gordon nor Earnhardt had been much of a factor, instead biding their time and waiting for a chance to move.
Gordon did it when he came out of the pits second behind Burton with 45 laps to go, and Earnhardt was fourth. Earnhardt pitted again when the final yellow flew with 20 laps to go, emerging sixth for the final run.
After Gordon passed Burton and began to pull away, all eyes seemed to be on The Intimidator, a notorious bad boy with the bonus looming.
The victory was the second of his Gordon's career at Richmond. He won the spring race on the three-quarter-mile oval in 1996.
The race was slowed eight times for 57 laps by cautions and had 16 lead changes among nine drivers. Gordon's average speed was 99.870 mph.
Rusty Wallace, a short-track specialist who had led 935 of 1,900 laps on tracks shorter than a mile this season, led 88 of the first 178, then fell off the pace until a blown engine ended his evening. He finished in 34th place, only his fourth trip outside the top 10 in 25 tries here.
