For gaming, the 1090T, or any amd cpu for that matter is not a great choice for gaming.
Most games depend on 2-3 fast cores, makint the extra 3 cores of the 1090T largely irrelevant.
Intel cores are faster on a clock for clock basis too.
Read this article on <$200 gaming cpu's. Even the lowly $90 G860 does better.
With your cpu budget in the $200 range, I might suggest a intel 3570K. It is as good as it gets for gaming.
And... see if that graphics card can't be upgraded to a GTX670 or 7950 class card.
A stronger graphics card is the key to good gaming.
