When Sims2 first came out, I went to a store and told the salesperson that I needed a decent gaming machine.
The %#*((!! guy sold me an HP pavillion a307x. 80 gig hard drive (sorry!) 2.6 processor speed, 512 memory stick, 250 watt power supply, and integrated graphics.
Yeah, that sucks, I ended up searching the net and travelling to a city an hour away to get decently spec'd parts when I built my computer. Salespeople love those media centre type machines. Like being given a tricycle when you really wanted a Harley.
