Yes, it'll work just fine. As it's an older motherboard it only has PCIE 2 slots (graphics card is PCIE 3), it'll still work there just may be a slight drop in performance. I'm not sure on numbers, but I wouldn't imagine it's too noticable with a card like that. It would be more noticable with a more powerful card.
Thank you so much, i was starting to get worried that i have to buy a new motherboard etc.
