Now, I am planning within the next 12 months to replace my mishmash of different screens with 3 identical ones and then after that upgrade to a top-end video card (probably the GTX 880 by that time), but that is going to have to come after this system core upgrade.

EDIT: I should also point out that my current rig can run the combination you've described at about 14-18 fps, not great, but smooth enough to cope with. I'm hoping that a much newer and more powerful processor with a much faster memory is going to improve on that significantly.

Weird, i remember that they'll be around 600USD, not 1K. If that's the case go with Haswell then thumb.gif

For future i recommend Nvidia GPUs with much VRAM possible, because you will eventually switch to P3D V2.0. I'm currently using it and very happy so far

CPU-Z lists my 4770K at stepping C3 classification. I think that definitively answers your question.

The question, though, is which stepping should I look to buy and which ones should I avoid? Simply saying that there are steppings doesn't change much unless some are better than others.

I think you mean which batch smile.gif


so far its L308B2xx or L309Bxxx or L310B4xx that are great, especially L310B4xx - this can apparently do 5ghz at ~ 1.30v or lower.

Well that's if I compare it to a few 100 samples I've seen on the web..

Mine is L308B202 and it can do 4.7Ghz @ 1.278v.

You're looking for revision and there's only one: C0. Stepping doesn't change AFAIK. Batch numbers are useless to go by today. I have a great batch number chip supposedly, yet it's a POS.

I had already purchased the CPU by the time these last few posts were made, having been under the impression that there was nothing that special to look for. As it stands, I've got one from batch 3334B909 manufactured in Costa Rica. The question now is whether its worth the effort of pushing the Micro Center where I bought it to allow me to rummage through their stock of processors to see if I can find one from the correct batches, or if I should just stick with what I've already got. I will say that considering the fact that the batch I pulled is not even close to the ones recommended, and knowing the way shipments of product generally work (most individual products in a shipment will probably be from the same or similar production runs), I'd say its unlikely, though not impossible that I'd find a good one out of what they have available. Anyway, the box is still sealed right now because I'm waiting at least 4 days on the DDR3 memory to arrive, so I'm looking for input on best course of action to take while I still have the option.

Thanks again.

I went from a C0 QX9650@4GHz to a C0 4770k.

Tbh, what I am getting is a big "meh".

There's zero difference in 99% of the things I do. So far, the only game where I have noted a difference is Rome II: Total War which uses thousands of very high resolution soldiers at some campaign maps.

C0 stepping was bad, you are correct. I expect the E0 stepping to be the anticipated "Haswell Refresh" just like it happened with the Q9550, where in the Q9550's which were released in November 2008 were E0 and the Q9550's which were released in November 2007 were C0.

Whether I get that same "meh" feeling or not, I am often pushing my current system towards full CPU utilization and the Q9550 is definitely not the QX9650. I'm not sure whether the E0 stepping is going to be that much better than the C0 stepping, but with a release date at least 6-9 months in the future, and my system being 6 years old, I feel that now is still the time to upgrade. Plus, there are more than a few out there who really love the Haswell, and also more that bring up the point that while the refresh will probably be of some benefit, its going to be an incremental improvement, not some magic bullet.
