I get a lot of lag spikes both in gta 5 and rocket league even on the lowest settings. I upgraded my gpu from a 750 ti to a 1050 ti just to get rid of the lag. On gta 5 with low settings i get like 60-70 fps but its not smooth frames... With rocket league I get 120 fps and I get occasional lag spikes on low settings as well.
specs:
GTX 1050 TI
AMD FX 6300
MSI 760GMA-P34FX MOBO
8GB DDR3 RAM
1 TB HDD
DEEPCOOL CPU COOLER
