I would like to buy a MSI R9 280X display card but I am concerned about whether it's compatible with my PC which is already 2 years old:

Z68 Extreme4, SandyBridge 2600K, BIOS 1.70, windows 7 Home Premium (64bit).

I am worried that if it requires updating BIOS of this motherboard, ASROCK only has the 'Ivy Bridge compatible' BIOS ver. 2.20 and beta bios. Is it fine to update this BIOS to my SandyBridge PC?

I am really puzzled about the use of 'Ivy Bridge compatible' BIOS to my SandyBridge PC?
