Oculus VR dev system

Hi,
i want to start develop with unity and Oculus VR.
My company is interested in computer vision and augmented reality system.
My system is:

CPU: AMD Phenom(tm) II X4 965
RAM: 16 GB (4 x 4 GB 1333 Mhz)
MOTHERBOARD: ASUS M4N68T
HD: Samsung 850 250 GB SSD
GPU: RADEON 280 or 290 (i'll buy a new one, i'd prefer the 280 because with my MB the performances of 290 are lower cause of bottleneck...)

is this setup enough ? I don't want to develop complex videogames, i need only to try some experiment with VR.

Thanks,
Igor
