Your components would run identically in any motherboard. The more expensive motherboards with overclocking/voltage stability etc are only needed for high-end graphics card and CPU's that you're overclocking.
For games, that CPU won't be stressed much as the graphics card is the bottleneck.
Bottom line is if things are stable then that's great. If you decide you need more performance then get a better graphics card. Either way your motherboard will be just fine.
