So recently I've been giving some consideration to picking up a gaming PC. I haven't really played the latest PC games since about 2005, and my MacBook Pro from June 2006 clearly cannot cope with the latest titles. It can, however, still provide more than adequately for my day to day needs, so I'm literally looking at a PC (or laptop, but I expect a desktop is the way to go) for gaming purposes.
I don't need some all powerful behemoth that is futureproof. Something that runs the likes of Left 4 Dead 2 and Team Fortress 2 without complaining would be more than adequate. In terms of price I was hoping for something around £500 all in, though I have no idea how realistic that is.
I also don't know what I need in terms of the more technical specifications. Which is why I turn to you fine people. I expect I'll be looking at buying more than building (because I would need to find someone else to actually do the building), and don't mind buying second hand for the right product, but I need to know what I need to be looking for first.
So, any advice? I'm more than happy for people to cover the basics for the sake of completeness. I'm also more than happy to people use their own gaming PC specifications as examples. If people are actually selling gaming PCs at the moment I would be grateful for a guide as to price (though this is not a FS/FT thread).
