So I'm thinking about getting back into PC gaming and am planning to purchase a dedicated gaming desktop. Been away from it for awhile so I'm way behind the times. I don't know what the best graphics cards are or any of that kinda stuff. What would you say are the minimum specs needed to be able to run most current games smoothly? I'm not looking for top of the line. I'm just looking for an an adequate setup where I'm not going to be behind the times in a year. And I don't want to have to run every game on the low resolution setting. A "mid-level" machine is what I'm looking for I suppose. And what about Alienware? Are their machines worth the $$$? Or can I build one from another brand with similar specs for a lot cheaper?
