Video Cards usually cost more than the motherboard.
If you want something that will last your years, without problems; Then you should change your motherboard and video card. Its a few more dollars for a lot less hassle.
BTW - I'm not sure if that 350W Power Supply with the case will be enough.
You should honestly wait a bit and get a bit more money. Maybe down-grade the CPU and get a much better video card. Also are you going to be overclocking?
