Surfing the web with multiple tabs in Chrome was very smooth and even having multiple apps and multiple tabs in Chrome was handled fairly smoothly as well.

Reviews Word on the street for the Intel Core i3 2125

The Intel i3-2125 is a very easy to use processor that will handle almost all current-day tasks without a hitch.

What People Are Saying Give it to me straight

Socket Type

Originally with an MSRP of $159.99, the processor can be bought for $119.99.

I would suggest using the current top-end i3 processor, the i3-3225, as it utilizes the Ivy Bridge architecture, has a lower TDP, and probably a bit faster.
by funfortehfun (Oct, 2012)
However, the Intel HD 3000 graphics aren't the best for GPU-accelerated web browsing and such and certainly not gaming.

Upon opening the box, Intel packages the processor, an Intel i3 stock heatsink (different from the i5/i7 heatsink in that it does not have a copper slug at the contact point), and a manual.
by funfortehfun (Oct, 2012)
The coil whine coming from the PSU I had used in the build (CX500V2) was louder than the heatsink's sound output.
by funfortehfun (Oct, 2012)
After booting the PC for the first time, the sound level of the stock heatsink was remarkably low.

The low TDP is perfect for an HTPC setting, which I used it for.
by funfortehfun (Oct, 2012)
Its price and low power draw are enticing to many budget gamers and HTPC builders, respectively, and HyperThreading may be of use to budget photo/video renderers.

After installing the processor in the socket, the force needed to secure the processor was much more than any AMD processor I had installed, and during installation the motherboard produces a sound that for newcomers like me may sound like the motherboard is about to break and shatter to bits.

Type of CPU

The Sandy Bridge processor market has steadily fallen down, and with that price.
