Yes, there is, The best that would work safely in the board is the FX8350, I'd look into the FX8370E as its a 95 watt chip run cooler and I would trust it more than the 8350 in that board since the FX8350 is a 125watt chip. The FX8320 125watt or the FX8320E 95watt are also a good option.
I strongly recommend that you look around for a 2nd hand (used) FX8xxx CPU, I do not recommend buying them new at full retail price.
AMD FX is old and out dated, If you can afford a new system, a New AMD Ryzen or even an i3 6100 which yes has only 2 cores, but often beats the FX8350 8 core in pretty much any game. With the i3 6100 it gives you room to upgrade to an i5 or an i7 skylake later. AMD Ryzen uses the the AM4 socket which I would think would be around for awhile, But you will have to get DDR4 ram for either platform.
There are older Xeon systems or older Sandybridge or Ivybridge Xeons, i5 or i7s that well perform even better than the FX8xxx and the FX9xxx.
So if the FX series is outdated, should I look at getting an I3 or even an I5? If i do, do i need to get a new motherboard?
Yes you will have to get a new motherboard, and if you go with the newest i3 or i5 you will have to get new RAM as well. It's well worth it, any lower end i5 will be faster than any AMD FX CPU for gaming. If you go for the new AMD Ryzen CPU, you will also have to get a new motherboard and RAM as they are DDR4. An i3 6100 is a good option and its always way above AMD in games for only $119 USD, You can get a cheaper h110 or h170 board for the i3, and 8GB of DDR4 ram and you will be set and you will have a upgrade path for an i7 later. You can use your old PSU and Case and storage devices.
But if you are on a budget, the FX 8 core will still do alright in games and is much better than the FX4300, But I don't recommend to buy a brand spanking new FX CPU if you go that route, the FX8320 being the cheapest 8 core is not worth $160 USD new, If you can find it for $100 bucks its a alright deal since you already have a compatible motherboard.
