Here's a trip down memory lane for you. OK, so it's not a very long trip, but I'm sure given the speed at which technology develops, it'll be nostalgic!
So, what am I asking here? You've probably guessed already... what PC spec were you running a whole five years ago?
Just think... so few megahertz, such a small hard drive and you didn't even care about the output of your PSU. What miraculous programs could your system rip through; what games?
Even if you can't afford that lovely SLI/dual core system you've got your eyes on, looking back on what you used to put up with should cheer you up.
