At least nowadays they have the decency to include vt-x in most models. In the C2D range the exact same model came with all three combinations:
And telling people, they have to buy AMD, is no terrorism?
Power consumption is a matter. I live in Germany, I pay 0.25€/kWh (~0.338USD). I did many calculations on currently (say: august until mid of october) available data, including the first BD-benches on those "bad" sites (anadtech, tomshardware etc.) - Taking the (at that moment) current workload, only the additional costs for electricity would give me a new SandyBridge i7, if things get worse even a i7 + Mainboard! This calulation was done for the usage time of 5 years (that's the minimum). So running the SNB for 5 years instead of BD gives me a new CPU for free! This calculation was based on the hope, that I would get a AM3+-Board with onBoard-GPU. As there is nothing like that ATM, There are further €30++ for a dGPU, further costs for power consumption. The i7 95W TDP are CPU+GPU, BDs 125 are CPU-only. So there are not only 30W more on the BD-side (read: by TDP, the actual plus in consumption is a different story), but >50W (depending on the GPU chosen).
And saying "hoo, the rest of my household appliances isn't powerefficient, so buying a power efficient PC is useless" is sort of stupid. If I can save good money with only one machine, I will do it.
BTW: 3000W for your oven is quite a lot. Mine (a Miele) uses 1000W, only takes ~5min. from 20°C to 250°C, and the big rest of the usage time it "idles". Using SB instead of BD gives me 1-2 big loafs of bread (self-baken) per week for free - incl. ingredients.
And now, I stop this useless discussion. Never wanted to start a flamewar, my first post in this thread was only about the uselessness of both "benchmarks" (running only one app vs. running as many CPU/GPU-intensive tasks as you can). It was last year, when I said, I need a new PC in 2011. All the months, I said "wait for BD...". BD was not what I expected, so I went for SB... i7 for 245€, and BD? 230€ for the 8150. And it is not available. So even if I would have gone for BD, I would not have been able to buy one... (Only the 4100 is available here, some shops also offer the 6100. All others are "Ohne Liefertermin"). It was my decision, I am happy with it, nevertheless I will recommend AMD-based systems when it is appropriate.
Core i5 2400, another resource.
Core i5 2500, with VT-x and VT-d
Its obvious you're getting torn up in here because you're just too stupid to hang. ;-)
FWIW, I have a Core i5 2400 in my media server right now. Without any copious amounts of research, I easily determined it supported the VM functionality I wanted.
An input/output memory management unit (IOMMU) enables guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping. This is sometimes called PCI passthrough.
