Venkatesh Duraisamy :
is i5 4440 is good?? or shall i go for any amd processors since my video card is hd 7770??
i5 4440 is very good, but if you can, try getting an i5 4690K ( should be around 15k in local stores)
and no, the FX8350 is not better than the i5 4440 in terms of gaming performance.
The FX processors run very hot too, and that is a bad thing in the already hot environment during summers!
