So recently after upgrading my pc to a gtx 760 gpu and a amd fx 8350 and a msi 990fxa gd65 motherboard i have noticed some issues with some game (massive maps). As when i run around in the map my fps is above 60 however for some reason i get wierd fps drops and when ever my fps drops my hardrive makes the searching sound. My gtx 760 and cpu are well cooled so there shouldnt be any problems with those. the only thing i havent upgraded is my ram and hard drive i wanted to know what you guys think the problem is? If so can you please recommend what i should buy to fix it.
