I'd say the real answer is if you do see any issues just turn the odd setting down a notch. I'm sitting it out on my 7600 until the next X3D chip has settled down in price.How does a CPU get bottlenecked if all threads are below 99% usage though? Are there any videos showing a 7600 with any thread running at 99%? Until I see this I'm still on the 6 core train with 7600 or 8600 next year.
AMD has made it difficult to find things due to having a CPU and GPU with the same name.
