Would you invest in a better PC for a next gen sims game?

Well since I really enjoy this game and it runs great for me I won't necessarily have to upgrade for awhile. So if the next one requires a system I don't have then out of the box then ... no. It won't be in my budget as a right now need. I do always eventually have to upgrade it's the way it goes so I will when I have too and I can afford it. Games usually work pretty well for me and I should be able to go with a standard good gaming rig that is current for that time period to run a sims game. I won't invest in something that is unusually high end for a Sims game because I'd be afraid that it might not support what's coming pack wise down the road.
If I had unlimited funds .. sure ;).
