How is your Nehalem or Westmere processor holding up in modern gaming?

So I could probably use a bit more voltage coming from 1.19v if I wanted to bump up towards 4.0ghz. (I'm 45nm)

Sounds like you're using a C0 920? Was able to get 4GHz using ~1.06V on all my D0s back in the day :

You said D0.

We're a ship without a storm
Cold without the warm
Light inside the darkness lit at peace

I know it's zero, but I always read Dio.

No I've got a D0. I wasn't quite sure what to set everything to when I built it. So I knocked the voltage back a bit since the ASUS board seemed to want to run it high, set the OC to around 3.6 and memory at 1333 ran some Prime95 and when it passed I left it. I never optimized for the max clock speed

So if I want to hit 4.0 set the bus speed to 191. What do I do with QPI? Also I'm not sure how much head room I have on my memory.

If anything, my main problem is probably going to be thermal headroom. The case is cramped and I don't have the largest heat sink. Just the largest that will fit.
