A couple days ago there was some discussion about how various CPU's perform with 780 Ti's, specifically at larger resolutions. Since I have access to a 3770K and a 3930K I decided to run some quick tests to see what the differences would be, so I'm going to drop them here.Test Setup(s) and Methods (Click to show)

I played in the Official 24/7 Siege of Shanghai server with a full 64-players. I used Precision X with the latest Rivatuner version to record data, and I basically recorded and entire round with both machines. I clipped off the beginning and ends to get rid of junk data during loading and score screens and also to get the same length of time for the graphs. They were fairly long rounds in which I basically went everywhere on the map. I spent most of the time on foot but probably five minutes or so in each run in a tank. Most of that time was spent third person view but some first person in the tank.
Below is a screenshot of my in game settings used to gather the data.
My Thoughts (Click to show)
Here is the FPS graph of the two runs.
3930K by about 13% on the average. My thoughts in another spoiler below.
It was about what I expected. The 6-core machine won out by a roughly 13% margin. Game play was really quite great on both machines, but there was no question the 6-core was just a beast. At pretty much all times that really mattered the game play was great on either machine. The minimums and the dips that show up in the graphs were things like me going under water, FPS dips after I died if I got blown up hardcore by something, etc.
If you got the money, obviously the 6-core will give you the best experience. I think it's biggest advantage, outside of the obvious physical cores as opposed to threads, is that it can off load background tasks onto the other threads and devote a full eight threads to BF4. That's just my suspicion, but I have no real way of proving that.
I will say at this resolution with a single 780 Ti, you'll have no issues whatsoever with a 3770K/4770K, etc. I played a little on the 3770K with a single card and the card is just absolutely tapped the entire time at this resolution. It may be different on single monitors, but at 5760x1080 a 3770K will push all a single 780 Ti can chew. Game play and frame rates are actually quite good with no MSAA and the High texture setting.
One last note I have to mention about the 3770K machine. I don't know if this adversely affected my results or not, but I can definitely say that an AX 860 is not enough PSU for 780 Ti SLI with Sky's bios. As the score screen popped up after the round ended, the OCP tripped and shut the machine down. I honestly kind of expected that to happen and was surprised it went as well as it did. I had my data so I wasn't too worried. Just wanted to throw that in there.
