Welcome...
...WELCOME to OCF Pedromvg.
Honestly with these parts you list as already having > Memory ram: corsair 4 GB 1600MHz CL9 DDR3
Graphics card:Nvidia GeForce 8800 GTS 768MB < you are in need of much more than an FX-8350 motherboard.
1. AMD FX processors don't even begin to catch up to Intel processors and never catch them in most gaming until you overclock the AMD FX processor.
2. Probably the better FX setup is done with 'two' sticks of DDR3-1866 ram so using two sticks can allow for a faster use of ram in Dual Channel mode.
3. Overclocking the FX series of processor and most especially the 8 core FX processors requires more than a stock heat sink. Something nO less than a CoolerMaster 212 EVO need be considered for a medium overclock of about 4.4GHz using an 8 core FX-8350. Just a fact of life found in going on 3.5 years since AMD FX 8 core processors have been released and we have had to deal with users now all that time.
4. Cheap, entry level motherboards and an overclocked FX-8350 just don't seem fit for each other very well, so we hardly ever recommend them. The only cheaper AM3+ mobo that might be worthy of mention when knowing an overclock needs to happen, is the GA-970A-UD3P motherboard. It is relatively new on the scene and is the very least expensive thing I would even think to recommend to one of my close friends, much less someone seeking a truthful suggestion in a forum.
5. I think if I were in your position and hopefully did not already have an FX-8350 in hand, I would get a much cheaper AMD FM2+ APU rig and use the money savings to get a better video card and kit of ram in two sticks so I could utilize the faster dual channel ram mode. Now this is my honest better choice for the money suggestion. What you do is up to you of course since it is your money. In #4 above, I have already mentioned the only cheap motherboard that I could stomach for a friend.
Whatever have some fun and good luck.
