Well, I suppose I can go with the 460, if you really think it outperforms the 550. That puts me just under 800, which is perfect, gives a little wiggle room for a monitor. I'll shop around craigs list, ebay, and amazon for a deal on a monitor. And I really ought to snatch that 2500k before the deal is over...
Thank you all so very much! If you have any more recommendations, even some games you think I should get (no, I don't want any of those modern shooters, too unrealistic.).
EDIT: Will I need any additional fans for cooling? If so, any recommendations?
