Yes the board is good. Though your system is completely not optimized for gaming.
There is NO need to go with an X58 system for gaming with anything less then 2 GTX480s which would run you about $1000 just for the cards.
I'm unsure on your budget but would suggest getting a AMD Athlon II X4 build with 4GB of RAM and a ATI HD 5770. This type of build should run at a similar price to your current one but would performance much much better.
If you want some good build advice go post in the "Systems" section.
