Very nice, with the red lights it looks a bit like mine

See some CS5 benchmarks here. Newer applications tend to scale quite well using processors that support more threads.

Many video encoding applications do even better with more cores. See some video editing benchmarks here:

You'll find the same thing with many new applications now (specifically designed to take advantage of more cores).

From my perspective, it just wouldn't make any sense to buy a new PC without going at least Quad Core, since the CPU cost is usually a small percentage of the overall system cost (case, PSU, motherboard, memory, hard drives, operating system, etc.).

Some apps scale really nicely with more cores. Bibble Pro is one example.

I've got both dual core and quad core machines, and the quad cores are noticeably faster with many apps that I use.

The difference between AMD and Intel, Intel quad cores use 8 processors - 4 cores + 4 hyperthread cores

and show up in the device manager as 8 cores




Applications that are CUDA (GPU) enabled run a lot faster

I ran a test to transcode a section of video with just the CPU and It's 8 cores it took 1 minute

8 cores are shown working here



I ran the same test with Nvidia CUDA enabled and it took 27 secs

PS. One of my other PC's has a dual processor and shows up in the device manager as 2 processors

I've always been fond of Intel CPUs and Nvidia graphics cards.

But, chances are, I'll boycott Intel going forward, thanks to their approach with Sandy Bridge.

Intel decided to include both hardware DRM and a "kill switch" that allows remote shutdown of a PC of it's using their latest Sandy bridge chipset design. Here's one article about the new kill switch "feature":

http://www.tgdaily.com/opinion-featu...te-kill-switch

This should get interesting as time passes, since as soon as hackers figure out how it works, others could probably wreak havoc with this feature.

I haven't seen any details on how this "kill switch" is supposed to function or what safeguards are built in to prevent unauthorized use. But, I sure don't want a PC that can be shut down by someone else remotely, period. Someone is bound to figure out how to exploit vulnerabilities with this design, and I don't want to be the person on the receiving end of that type of exploit.

As for it being an anti-theft feature, anyone could remove the drive and read it's contents after the PC was shut down remotely unless it the drive was encrypted (and encrypting the drive would be a much better way to go if someone was concerned about theft).

So, I probably won't be buying any more Intel CPUs as time passes, as their newest features are just a bit "over the top" from my perspective.

IOW, if buying a new PC right this second, I'd probably take the same approach that Dustin did (buy a 6 core AMD CPU), as I don't like the direction Intel is taking with their latest chipset designs (even though most of my PCs are using Intel CPUs right now).

Not enough information on the kill switch is available as yet, so I'll leave my opinion until more is known
