This is a dual core processor clocked at 3.1GHz, Bought this for a HTPC build, was combined with 4GB of DDR3, a Biostar H61MH motherboard, 1TB HDD and an IOGear wireless keyboard. The computer is really fast and works great as a HTPC, its plugged into our 42" LCD using the HDMI port at 1080p. The video looks great even though the motherboard doesn't have a dedicated video card/chip. I've even played movies on XBMC while ripping a video at the same time, without any problems. All our videos (mkv and avi) look great, so does Hulu desktop. I haven't run any benchmarks but I do know that it rips videos about 50% faster than my Core2Duo Macbook pro.

The processor was well packaged and easy to install. With only a 65W power consumption, it seems to run cool all of the time, only heard the fan speed up while installing the OS. The fan that came with the processor seems more than enough and quiet, though I did use Artic Silver 5 thermal compound with my build. The other thing I really like is how you don't need an additional graphics card, keeps the cost lower and also reduces power consumption indirectly. Note: this can't be over-clocked.

All in all, a great CPU, highly recommended. Will probably install Ubuntu 11.04 soon, will update the review then, especially if there are any problems.

There is so much hype surrounding the i5-2500k that most other chips get overlooked. This is one of those gems.

For starters, this is a FAST processor. 3.1GHz w/a 3MB L3 cache. That is QUICK. Plus, it is a dual core (most programs & games cannot even use quad core, so why bother?) and it has hyper-threading, so it actually seems that it's quad core. It's built on a 32nm technology which makes it one of the most power efficient processors available. On top of all this, it runs SO unbelievably cool, that I still have a hard time believing the temperatures in my case.

It has some graphics stuff inside of it that I still don't fully understand, but I guess that is awesome.

Cons: It does not have the ability to be overclocked. If you want to overclock, the i5-2500k is for you. If you want a very nice system, with a cool-running, inexpensive chip, then GET THIS. YOU WILL NOT BE DISAPPOINTED.

Final thoughts: I think that this latest build is the best computer that I've ever owned. I am so thoroughly impressed with every aspect, including Amazon's incredibly fast shipping and packaging.

I built a SandyBridge gaming rig last month. I chose the Core i3-2100 as a cheap option to see if it would be great for games such as (StarCraft 2, Crysis, Crysis 2, Burnout Paradise, Left 4 Dead 2.) I am very impressed at the performance level this processor offers. First the Benchmark. I used Passmark Performance Test 7. The score was 4,472. Compare that to my Core i5 based MacBook Pro which was 2,367. So far I have yet to push the limits of this processor. I would Highly Recommend this processor over any AMD for low budget gaming.

The Specs of my gaming rig

Intel Core i3-2100
8GB of DDR3-1600Mhz RAM
Asus P8P67 Deluxe
Geforce GTX 460 SE (which is an underrated card)
2TB WD HDD
Samsung Blu-Ray Drive (Reads BD, Burns DVD/CD's)

I used this CPU as part of a build to replace my AMD Phenom II x3 705e / HIS HD5670 based HTPC. I was not happy with the picture quality and power consumption of the AMD-based system. After reading a lot of reviews, forum posts and finding the right sale, I took the plunge. I am so happy I did.

The picture quality of the integrated HD2000 graphics is just amazing. It blows away the HD5670 discrete graphics I had installed. There is far less color banding, especially in dark scenes. This is very evident when viewing the scene in How To Train Your Dragon when the father is speaking to the son in his room at night. I've found too that panning DVDs looks much better. Again, my test for this is the opening scene to A Charlie Brown Christmas when the scene pans to the pond where the kids are skating. (Can you tell yet I have kids?). It was very easy to setup HD audio bitstreaming. Everything has worked without a hitch with the exception that I currently cannot update the Intel IGP driver without getting a BSOD. The driver version I have though is stable and works so it's a non-issue.

I measured power consumption of my system from the wall using a kill-a-watt. The new HTPC is basically the new i3-2100 CPU and an ASUS H61 motherboard with all the same parts reused, except the HD5670 GPU. Power consumption went from 180W-200W watching video/TV to 40W-50W. It clear too it's throwing a lot less heat because the fans in the same case are running a lot quieter. Idle power went from around 90W to 28W. So, basically, this doesn't use more than the power of a 40-60W lightbuilb whereas before I was using a chandelier ;).

Main reason for purchase of this CPU was its energy efficiency. I wanted something fast and still have a low power consumption and so the Atom processors did not fit my needs.

When the computer is sitting at desktop it currently pulls 28W and Under full load it never goes past 37W. The whole computer consist of a 400W 80 PLUS Bronze PSU, an F3 Samsung hard drive, using its built in graphics chipset for video, single module 1333mhz 4gb DDR3 ram, a single 80mm fan, an asrock h67 motherboard, and DVD burner.

Fits all my needs

-Transcoding speeds are reasonable (although I did not buy this CPU for that) trough quicksync feature
-Windows 7 runs quick and snappy
-HD 1080p YouTube and Netflix play fine without any struggling. Played both at the same time without cpu utilization going beyond 55%

Nice CPU for "general" computing. Would recommend if your needs are similar.
