I want info abour my gaming pc

Hello everyone ,

I recently did major changes on my pc but I want to know your opinion about the specs in general and the CPU i'm going to buy in 2 day (it's the only 1 they got in sale from here).

One of my friend gave me a GA-990XA-UD3 and 8GB Corsair Vengeance 1600Mhz.
I had a ASUS GeForce GTX550Ti ,OCZ PowerXStream Pro 500W and a AMD Athlon IIx3 460.

I was wondering if the FX-4100 could have a greater performance in most of the game since my Athlon II x3 460 is getting broken due of overclocking.

The AMD FX-4100 was the only processor remaining in the store  

Thanks.
