Okay, so I've posted twice before this about building my first computer. First I stated I wanted a decent gaming computer for $625 and then in a second thread I realized I would have to increase by budget to $1000 for what I want. This would mean I would have to save for another 2-3months. Should I slowly buy each part over the next 3months ? Or should I buy them all at once when I have the money because any/all of the parts be obsolete compared to newer models coming out till then.
