Anybody test 3770K w/HT on/off in BF4?

I'm currently rocking 3570k @4.5GHz with 7950 in my gaming rig. I recently downloaded BF4 Beta and have been playing it a bit here and there. I get generally very good performance, with occasional "rubber-bending" which is most likely server side network issues. BF4 is definitely taxing all 4 cores quite a bit. Switching to task manager I see all cores at about 85% utilization while playing. I know BF3 (which I play as well) and now BF4 are capable of utilizing up to 8 cores, (BF4 probably more so now), I was wondering if going to a similarly clocked 3770K w/HT would give me better (smoother) gameplay... I got a Microcenter near by, and can get 3770k for $250, then sell my 3750k for 180~200 (according to latest eBay bids) so a $50 difference in the end. Would it be worth it? Can anybody test it for me on their system? Pretty please...

on for sure. bf4 may be one of the few games that benefits from hyperthreading, as it will prevent thread waits due to 100% core usage.

i have a 4930k and without hyperthreading it will go 100% and cause stuttering, but with it will smooth out. All 12 threads show ~50% usage so between the game and the driver they are all being used! kind of nice actually.

dice did release a patch today to help with CPU usage.

Grab 6 core and you'd have smooth gameplay, otherwise don't bother.

There's a little more to upgrading to 6 cores than just "grabbing." It'd probably cost the OP 3X the cost of going HT. Until we have final rigorous benchmarks of 6 vs 4 cores with HT it's really not fair to say what is the better move.

FYI I have an I7-970 (at 3.35) with a 6950 2GB at 1920x1200 and it uses all 12 threads but half of them are only about 10-20% with the others at 40-80% at best guess. I was running task manager on my 2nd monitor. I didn't notice much of a CPU usage difference between the high and ultra settings and I didn't use any other settings. A quad with HT should be fine for BF4 but then again that is the beta and only 1 map. A quad without HT will likely be a bottleneck but but not by tones. I got 20-30 FPS on ultra and 30-40 FPS on high. My video card is holding me back by quite a bit but my 3 year old CPU is still overkill . Also note that BF4 is not that RAM heavy, it only uses about 2 3/4 GB of RAM. I didn't measure VRAM usage.

Normally HT cores report n for one, m for the other, where n + m = 100 when they are at the same efficiency as a non HT core, > 100 when they are more efficient, and < 100 when they are running my programs or Linpack.
