What's currently hot? My system is quite moderate now, but still performs amazingly. i7 2600K and GTX580 SLI. OCZ Vertex 3 and a 120hz 27" display. It's lighting fast at everything. Using it makes my Retina MacBook Pro seem sluggish. So fast at everything. Super responsive, and the 120hz display only makes it seem quicker. With a stupidly quick 120Mb internet connection, it's mental. In normal use, literally everything happens seemingly the instant you 'press the button'. Always. No exceptions. It's a game rig for the most part, and even now it manages 60fps on ultra settings in any game I currently play. Level loading times are crazy fast, too. The point being that modern PC hardware is so capable it's almost funny. I can't see me upgrading for a long time. FYI.
