Trying to learn, but this is my first time building my own computer and running out of time so could really use help. It can't be much more than 550 dollars, including buying windows, and it needs an optical drive too. Mainly I want to play starcraft 2 on it, but other games too, if possible. What I've heard is that an intel pentium G3258 and something like an evga GeForce GTX 750 Ti (superclocked or ftw version) would be good, but wanted to double check here. Would that work ok? What would be the best parts and case to go with it?
