The reason I mention Vista is because I am using Vista myself with not much RAM itself. Seeing I can't really afford one of those "High-Def" computers that kids have now a days, it worries me seeing I am limited to much gaming. Thus seeing I don't think a graphics card even for Vista would support it well enough until then.
But on the other note, Vista is going to be Out-of-Date soon which is very worrying to me seeing I still use it. Prices are in the range where I can't afford it right now but hopefully I'll be getting a job soon and seeing what can happen until there. But for now, I'm living the days left of Vista as the numbers count down.
If you have a good suggestion of what kind of computer I should aim for (One with good RAM obviously) that is a decent price, please let me know seeing I am probably going to miss Vista since it was very helpful while it lasted.
