As for impact, I got to go with the Bama-Texas national championship game where Colt was injured. Mack was never the same after that game. And Texas began a long spell in the CFB wilderness.

Loss to TCU in 1962.

1961 loss to TCU. The loss cost Texas a national championship.

The Longhorns defeated Arkansas (33–7) and Oklahoma (28–7), and were ranked No. 1 until they lost, 6–0, to unranked TCU on November 18. At the end of the regular season, the Longhorns were ranked No. 3 in the final AP poll and No. 4 in the final UPI poll. They concluded their season with a victory over No. 5 Ole Miss in the Cotton Bowl Classic.

Yes, 1961. I was a freshman then. My bad. That's the one I meant.

The Texas Tech loss in Lubbock with the Michael Crabtree catch has to be up there. Kept us out of the national championship with a team that many think was better than our 09-10 team that lost to Bama in the Championship.

Particularly brutal because we should have won that game. Mack didn't run down the clock before we scored. The Gideon dropped interception. The two players missing the tackle on Crabtree after the catch. Brutal

Some of the impactful wins and losses during the 60s :
1) Loss - 1961 loss to TCU as mentioned earlier. Cost Texas a national championship.
2) Win - 1963 win over #1 Oklahoma, 28-7. Propel Texas to #1.
3) - Win - 1963 win over a very good Baylor team, 7-0. Baylor was led by all-Americans QB Don Trull and WR Lawrence Elkins.
4) Loss - 1964 loss to Arkansas, 14-13. Cost Texas a national championship. Kenny Hatfield ran a punt return for a touchdown. Texas rallied. Coach Royal decided to attempt 2 points conversion for the win, instead of a tie. Passionately failed.
5) Win - 1965 Orange Bowl (after 1964 season) win over Joe Namath and #1 Alabama. This was the first night time telecast of a bowl game.
6) 1968 - Loss to Texas Tech, 31-22. Texas was down 21-0 at halftime. Coach Royal put in James Street at QB to start 3rd quarter Texas rally fell short. With James Street at QB, Texas finished the season #3 in the AP poll. After this loss, Texas started a 30-game win streak from 1968 to 1970, contributing to two national championships.
7) Win - 1969 win over #2 Arkansas, 15-14. The 1969 season marked the centennial of college football. This was described as the Game of the Century.
ABC television executive Beano Cook had arranged for Texas and Arkansas to play the final game of the regular season, moving their usual October date to the first weekend in December.
President Richard Nixon attended the game and established it as a national championship game by announcing he would award the winning team a presidential plaque declaring them "the number-one college football team in college football's one-hundredth year."

The game was the all-time highest Nielson rating for college football games for years afterwards. On a side note, the 2006 Rose Bowl is the most-watched college football game in U.S. television history, with 35.6 million viewers. Texas defeated top-ranked USC 41-38.

The loss that impacted me the most was the Cotton Bowl against Georgia. It still makes queezy to this day, There are two wins that are tied for me. 1969 vs. Arkansas and the 2005 BCS.
