Hey Spek,
Doing a quick look at what CPU s are compatible with your motherboard, I would recommend upgrading your CPU to either an AMD phenom II x4 975 or possibly an AMD FX 4350 quad core
The 975 is 3.6 GHz quad core factory clock, the FX 4350 is 4.2 GHz factory clock ( well 2 of the 3 I have are because they are the Black Edition models, the 3rd one is 4.1 GHz )
Upgrade your system memory to 16 GB if that MB will support it....I just did a quick check on what compatible CPU's it would take/handle
The nvidia 1060 is pretty good recommendation as well...
Hope this helps
TC
