Thanks! I was leaning towards the 5770. If I may ask another question, what makes a good case? I mean...I know it's about airflow, but there seem to be little difference outside of build material and whether there are fans?? I definitely want one that is cut for 120mm fans, as this will be in a smallish room and noise can make a huge difference. Also, how much power will I need for the 5770? I figured 500W would be sufficient for me, as I don't really plan on doing Crossfire.
500w is just enough.A good case is one that is nice and sturdy,can take a beating and does not build up dust(too fast)Of course if you utilize more fans dust maybe a problem.They do make cases that have 'sound dampening'but they are a little more expensive.It depends on the size of the motherboard and how much you will be gaming...if any at all.
