i5 2310 2.9GHz processor
Asrock H61-VS
R9 290 Tri X
H100i corsair cpu cooler
620w true rared PSU bronze
8gb single channel vengeance
WD 1TB Black

1080p
fps on farcry 3 : it can dip as low as 10 fps and 60 fps is the max vsync on bec. of screen tearing
on bf4 single player : min is 20 max is around 110 no vsync
crysis 3 : min is around 10 and max is around 60 no vsync

cpu usage is around 50-70%
gpu usage is around 70-100%

the problem is why do i have that very min fps

i watched some videos regarding 2310 and compared to 3770k
the min fps of 2310 is 22 fps and for 3770k is 44 fps

so do i need to change my i5 now? and what are your suggestions?
i do have a budget of lets say 150-200 usd right now

thank you pips :)
