I just got a new gaming PC at the end of May and I'll post the specs for it below just in case anyone is currently in the market for a gaming PC that isn't crazy expensive. I got my rig from CyberPowerPC and I am loving it so far. It runs TS3 flawlessly and the game just looks gorgeous. I can run the game on the highest graphic settings and I can play for hours without my PC even breaking a sweat. No more save errors (rejoice!) and in the month that I've had the PC my game has crashed only once.
My rig has an AMD 8 core processor (yes, I know that's overkill), 8 gigs of RAM and a Radeon R9 280 video card (3 GB).
I started off with the AMD 8 core
http://www.cyberpowerpc.com/system/Graduation_AMD_8-Core and tweaked a few things, like the power supply, the RAM and the fans - final cost with shipping was $1089. I already had 24" monitor, speakers and a keyboard so I left those items off, which saved a little off the final cost. I also didn't get the cool looking LED fans.

Anyway, I hope this helps someone. I'm thrilled because I should be able to run The Sims 4 on this rig with no issue. It is a BEAST! I know I'm missing an SSD drive but I can always add that in myself if I decide to....everything runs so well on my PC that I don't know if I'll bother. From the time I double click the game icon on my desktop to my save file being loaded and ready to play is about 2-3 minutes. Saving takes even less time, about 30 seconds to a minute.
If you do order through CyberPowerPC make sure to do your research first or have someone who is computer literate help you pick the components for your rig because apparently if you pick components that aren't compatible the guys at CyberPowerPC won't always contact you to let you know. I also strongly recommend using their official forum if you need help piecing a system together. The guys on the forum are incredibly helpful, knowledgeable and very kind.
Happy Simming, everyone!
ETA: Correction - I timed it last night and my PC actually takes about 7 minutes from desktop to having my save file loaded, ready to play. I have all EPs, all SPs except for Katy Perry and the Movie one. I also have quite a bit of custom content - mostly clothes, make up, hair and furniture. And I have some Store content.
