A few days ago, I bought a GTX 980 to replace my CrossFire 6970s. However, after I installed the GTX 980, all games were very laggy (spikes as low as 20 fps in very undemanding games such as osu!) and overall ran pretty poorly (went from ~250 fps in l4d2 to ~80-110; from ~500+ in osu! to ~300 with massive lagspikes which lag the shit out of everything as well as occasional 20 fps at seemingly random; from ~45 fps to ~10 or even single digit fps in H1Z1). At this same time, I bought a second stick of 4GB ram for my PC which, for some reason, bricked my PC when I tried to add it. I put my CrossFire 6970s back in, and even those lagged just as bad as my new GTX 980 when I put them back in.
Ultimately, I decided to go all the way and upgraded my i7 2600k to a i7 5930k, and my P8P67 WS Revolution to an X99-A, as well as adding 16 GB of DDR4 RAM. Good thing is that I can install all 16 GB of RAM on this new motherboard; however, games still have a big lagging issue, and even just typing this I can feel it: Games are running at decent framerate (~200+ in L4D2), however they dip every few seconds (in L4D2, for example, I can spike from ~200+ to ~100 or so, and these lag spikes are audible as well, in that they cause audio distortions). I hate reinstalling Windows, but it seems like it's the next step. Would you recommend it or think that could be my issue?
In each case of swapping GPUs I used a driver sweeper program to remove the old drivers and installed the new ones.
