Well depends how in to over-clocking you are. Like I said by IPC matches a phenom @ 4ghz ( cept in some older software) If I ran 1.45 volts through this chip I could probably hit 5ghz a good phenom can maybe get to 4.5 so again single core performance ends up the same but with 2 extra cores. You have to bare in mind an 8120 is 20-30 pound more than a 1100t, for it's price it does perfectly. The 8150 is completely waste of time though "Yes, Bulldozer has 8 "cores", but it shares a lot of resources between them. So, in workloads reliant on those shared resources, it'll perform like a quad. This is why you see Phenom x6 beating it in some threaded applications. In workloads that aren't so reliant on those shared resources, or that are a bit more balanced (e.g. real world multitasking), BD can start to behave more like an 8 core. However, the end result in benchmarks is the power consumption of an 8 core and often the performance of a hyperthreaded quad, and a lot of the bad press on launch was because of this. " Can you give me a few examples please, I'd like to try it out It certainly doesn't effect cine-bench ( I can disable one core per module with my motherboard and it didn't really make a difference compared to disabling the last 2 modules) But if you name what software is effected I can try and see if it really doesn't get an extra performance from those extra cores. I think people forget that two extra cores( over a phenomx6) doesn't necessarily mean 33% extra performance. Like going from single to dual didn't give us the 100% boost people would of expected. Now just to before I get barrages of " fan boy" If I was doing this build from scratch I would go with a 2600k set up. How ever I already had the 990fxa board so went with BD. But compared to my 1055t most things are quite a lot quicker . For example you would expect a 50 performance difference between a phenom 965 and 1100t stock at cinebench, but the actual performance difference is closer to 28% . It seems the hype killed these chips more then anything else.
