Personally I have found PC gaming to be more expensive.
Budget creep - I always end up spending much more on hardware than the initial plan e.g.
@Johnnypenso tells you to get a gtx970 graphics card. You know you weren't planning on it but hey "ultra" settings would be great wouldn't it....
I've never had one console get a problem in terms of physical hardware or virus problems. Personally I've had multiple power supplies die, multiple hard disks die, wireless keyboards, memory, fans, soundcards, mice all die, and then there's drivers and viruses..... I know things are better than they were but it still needs you to keep up with tech knowledge/windows and be very structured about where you store mods/software to use a PC for gaming. I'm tech savvy due to my previous career but it can be a pain. However Consoles give that immediate kick. It all works straight away.
If I had the money I would ABSOLUTELY get a super laptop capable of running Project Cars on maximum AS WELL as the PS4 I already own. However cost dictates that won't happen for a year or two. So when it's a choice for me, currently the PS4 wins.
I still think the Steamboxes (if they ever come out) will be a godsend for console/lounge/living room gamers as long as they allow you to connect to the same online game communities/servers as PC's.
For now I'll have to "settle" for a PS4 for Project Cars and Game Stock Car Extreme on my non hyper laptop.
