I did flash both of my cards to the Asus TOP BIOS using RBE and the WinFlash utilities from TechPowerup. I believe one of the only benefits to the ASUS TOP BIOS is that you can increase the cards voltage via ASUS' software, called SmartDoctor. Also, the ASUS TOP BIOS allows the card frequency on both GPU core and memory to go much further than the stock BIOS on the 4770s.
However, the funny thing is, ASUS never released a TOP version of the 4770. I believe AMD paid ASUS not to release it, because they were worried about something... although I'm not sure what.
Anyways, I flashed back to my original BIOS for each card, because I learned that a BIOS flash voids the warranty on my XFX and Sapphire card. If I am going to do any OC'ing, I am not going to use the ASUS TOP BIOS and increase vcore on the cards. I have overclocked these cards before while on the ASUS TOP BIOS, but I did not see a significant increase in performance. I didn't overclock them much, but I don't think its worth shortening the life of the cards just to get 3-4 more fps.
I may change my mind and decide to OC in the future, but I'm definitely not going to re flash these cards back to the ASUS TOP BIOS. Also, I recommend OC'ing with Riva Tuner and not using Catalyst Control Center's OverDrive.
If anyone is questioning their XFX 4770 being able to flash to the ASUS TOP BIOS, it is capable.
