Any recent drivers I should download for Chronos 7 (8770M)

Hey guys, can I get a little help with what recent drivers to download for my Samsung Chronos NP780z5e? It has a 8770M switchable graphics card. My AMD Catalyst Control Center data tells me it's the same card as AMD Radeon R9 M270X.

Currently, I am using 14.12 AMD Catalyst Omega Software.

Thanks!
