The Springboks face New Zealand knowing a win at Carisbrook - a place where no Bok team has won before - will give them their second consecutive Tri-Nations title.
"You can't make it any bigger than it is," White told superrugby.co.za.
"We win on Saturday, we win the Tri-Nations, we retain the title, we beat the All Blacks for a third time in a row and we go to number one in the world.
"You can't try and make it bigger than that."
White is convinced the All Blacks will beat injury ravaged Australia in Auckland next weekend, effectively making this Saturday's Dunedin clash the Tri-Nations final.
"I'm reluctant to say it but this is definitely the final because I can't see Australia going to Auckland and being able to beat the All Blacks with all the injuries they have," White said.
"As much as people say 'the All Blacks have to hold back for next week', I think the team knows this is like a final and whoever wins here will win the Tri-Nations."
