Two British players are among the five who still have a realistic chance of winning the FedEx Cup at the concluding Tour Championship in Atlanta this week.
Rose is currently third in the rankings after last week's BMW win in Chicago while world number one Donald is fourth in the race for the $10m (£6.4m) bonus.
Americans Webb Simpson and Dustin Johnson lead the standings with Martin Kuchar in fifth and although all 30 players have a theoretical chance, a win in Atlanta for any of the top five would secure the Cup.
Donald remains cool about the substantial financial gain he would accrue should he win in Atlanta.
"I'm not really thinking about the money,” he stated. “I'm really more concentrating on winning the tournament, picking up another trophy, all the spoils that come with it.”
“But the bonus money is nice. I've been very fortunate. It's not like I can't afford to buy things. I have two nice houses. I don't spend a lot on materialistic stuff."
The 33-year-old, who became world number one in May but missed the cut at this year's Open and is still waiting to win a major, is focusing on strategy for the upcoming challenge at East Lake.
"You need to put yourself in the right positions here and give yourself good looks," he added. "These greens can get quite fast, and putting uphill is a big advantage."
Meanwhile Rose, who beat the 70-man field to win by two shots in Chicago, agrees that the money and the game are decidedly separate.
"Last week the cheque didn't enter into my mind once until I saw the number [$1.4m], and I was like, whoa, that's a big cheque” he said. “This week, it's the first time it really gets people's attention and it changes and it's a big amount of money... thinking that way about it, though, doesn't help you play better golf.
"The key and the strategy still is to do what you do best, to use all your skills, to stay in the moment. What makes winning a huge challenge is to deal with the pressure of the $10m and keep your game in shape and in check."
However Mayweather, 34, has not shown any eagerness to get back into the ring. The American left a sixteen-month gap between fights the last time and Khan may have to wait rather longer than he would like to.
