I don't think it's worth the buy.
It's an old CPU and you won't find it for less than $50.
The G4400 would destroy that CPU in any game, without competition.
G4400 is a $50 CPU, pair it it with a H110M, but your problem is the RAM, you can't use DDR2 with a Skylake CPU.
I suggest you save up a bit of money and go with my above suggestion, I am guessing that you have a Core2Duo right now, so you can do basic tasks.
