I have 2 male boxers and have never had any problems with them fighting . I volunteer for boxer rescue and would say that there is more chance of 2 bitches fighting than 2 males but at the end of the day it really comes down to the 2 individual dogs. It concerns me that you think that there is a high probability of a White boxer being either deaf or blind but yet you were happy to buy a puppy without meeting it first? There is a higher rate of deafness in White boxers but they are still few and far between. I have a White boy and he's perfectly healthy. I paid £300 for him over 4 years ago so would be surprised if you found a healthy pup from a good breeder for £80.
