I wasn't sure whether to put this in the GPU thread or this, I can close it if there's any probs.

I wasn't really an enthusiast PC gamer until now, but I'm not the type to blow 5k$ in a PC either, just some things I wanted to watch out for with new build, make sure its working all good. I'm eagerly waiting for the 3770k and the thing is, for a game like battlefield 3, or a pc game that is well optimized or at least meets the standards, and considering you have a same generation CPU and GPU (3770k and gtx670 for example), what should the CPU and GPU usages be? should GPU be 99% and CPU be like 50%?
When is there a CPU bottleneck? Is it when the CPU is 99% and GPU is 50%?
What if both GPU and CPU are 99%?

PS. when i say 99%, i dont mean exactly 99%, just close to full load. Also did a poll to see how many SB ppl would upgrade, because I also considered getting SB now and Haswell next year.
Thanks,
Corsair Lagoon

The CPU usage and gpu usage vary by game. Some require more CPU power and some require more gpu power. Yes you are correct, when either your CPU or gpu is @ 99% and the other is not then technically you have a bottleneck. However, this is only bad/a problem if you are getting low fps. If you are getting 100+ fps with a "bottleneck" then it really isn't a problem. There are very few games that will run both your CPU and gpu both @ 99%.

wait so in a game like battlefield 3 with well optimized 4 core engine, i should see high cpu as well as high gpu?

If a game is optimized for 4 cores and you have a quad core CPU, then your chances of a bottleneck are reduced, and you will probably see high gpu and CPU usage.

Remember that having a "bottleneck" isn't really a bad thing unless your fps is low because of it.
