Transitioning from Cubase Pro 8 to Pro Tools HD

So I've decided I'm going to start my integration to Pro Tools HD. Me being a man of faith, this is taking a crazy leap in order to receive a beautiful blessing and also be a blessing to others in the end. This is my current setup:

Cubase Pro 8
Yamaha HS80M studio monitors
Focusrite Scarlett 6i6 audio interface
Focusrite Isa One Mic Preamp
Sterling Audio ST69 Microphone
M Audio Axiom Air 49 midi keyboard

Windows 8, 64-bit
HP ENVY 700-210xt CTO Desktop PC
Intel Core i7-4770 cpu @ 3.4GHZ
3tb hard drive
16GB ram
Intel HD Graphics 4600 video card
Just starting in a home environment does anyone believe I'll need to change my cpu? Would HD Native be my best route? Any input serves as great advice
