No it's not worth upgrading from i5 3330 to i5 4690 .May be 10 to 15% diff but you won't see much performance boost with that money to spend .If u wanna buy cpu /mobo ,then go with r5 1600 with the same price .you will see nice improvement. Whats ur gpu and monitor resolution?
If i'd buy the 1600 then I'd have to buy a separate motherboard and DDR4 ram which will cost another more or less 400$. As I said 230$ for both 4690 and the Z97 mobo. I already have 8gb ripjaw ddr3 ram so i wont need to spend for ram anymore. my gpu is GTX 960 which will be ugpgraded soon (it's good for now so no need to upgrade yet). 1080p is my res.
I really need to buy a new mobo because my 1155 mobo has problems with drivers which causes latency ( I use my pc for recording)
