Is this GPU compatible with my pc?

[jamesiamjames]

Hello everyone, i wonder if my pc is compatible with a MSI GTX 960 GAMING 2GB
Here are my specs:

motherboard: Medion MS-7797
CPU: Intel i7 (not sure which model)
RAM: 8 gb
PSU: 450 watt
current GPU: nvidia gt 620

i have a small motherboard so i don't know if it is compatible

All help would be really appreciated
