as a stock 2600k. So as far as I'm concerned, there probably isn't a CPU available that will give you a consistent 120fps in those big matches, even overclocked.
CPU bottlenecks are the bane of the 120Hz monitor (even the 60Hz monitor IMO). CPUs aren't really advancing to keep up with the GPU industry, and as I was saying in the other thread, these days you either have old games that are bottlenecked on one or two threads (You wouldn't believe how hard it is to run UT2004 at 120fps because of CPU bottleneck), or new games that simply saturate all threads. There are just a few games in between that are multi-threaded enough to avoid the former, but not too CPU intensive to cause the latter. Most of these are single player games that are inherently less CPU intensive. In things like MP 32 Player UT2004 or 64 player BF3, 120fps becomes an unrealistic target.
A lot of people like to say that CPU bottlenecks are a non issue these days, but they're probably the ones that are happy with fluctuating framerates and don't mind drops to 35-40fps. If you're going for a 'perfect' constant 60/60 or 120/120, CPUs become a huge problem.
I personally think 60fps is a realistic target for BF3, probably requiring a reasonably well overclocked 2600k/3770k/4770k to ensure 60 is maintained in big matches. And in my experience, you only need a single GTX 780 for that at ultra detail (assuming 1920x1080).Edited by Oubadah - 8/11/13 at 3:37pm
