Not really. Less power but concentrated on a smaller area results in higher temps.
However it's the crappy paste instead of solder what makes temps high afaik.
Try popping the lid, and it's fine.
I find most reports of high temps are running 1.3 V through these chips...THAT is why they "run hot".
I will have to disagree with you there, 2500K does indeed run cooler than the 3570 due to the poor heat dissipating powers of the 3570K. My 25w soldering iron is far hotter than my 65w cpu, care to explain that?
Really? Why don't YOU explain it?
Ivybridge doesn't have ANY heat issues. It's even got a higher tjMAX, yet lower TDP. Have you even used one of these chips?
But yes, the 3570K is superior compared to the 2500K in almost all measures, only if you choose to utilise them. Getting 1600Mhz ram? Not too much different between 2500k/3570K. Using 1866Mhz ram? 3570K wins hands down. You have a good heatsink? 3570K clocks almost as good as 2500K, and wins hands down. Sticking with stock clocks? 3570K stock is better than 2500K stock.
Again, memory write performance with some workloads, at all speeds, is much better on Ivy then Sandy...to the tune of 33%.
14% GPU usage is not a bottleneck, it is a problem with your system and most likely software/driver related.
This ^.
Figure out why you are only getting 14% GPU usage instead of much more, and you'll find the problem affecting ARMA II performance.
Your CPU does in fact bottleneck your GPU a bit, in comparison to Intel chips, with their higher memory bandwidth, and yes, it affects framerates in a few games. However, as I psoted above, F1 2010 performs FASTER, with a much "slower" CPU, so don't choose a single title as the reason to just write off your current system.
If I was you, I'd save up until I could buy a COMPLETE new system...motherboard, GPU, memory, PSU, HDD...ALL OF IT. What you have now is not optimal, but it's more than fine for what you need it for.
