The only AIO i found with a real desktop processor. This model could have the best price-performance ratio
on 3 November 2011
Processor: Intel Core i5 2320 3GHz
Video card: NVIDIA Geforce GT 555m 1GB GDDR5
BlueRay and DVD drive
1TB Hard Disk
Beautiful screen, just a glass front with touch buttons on the frame to adjust brightness, volume, etc. Speaker bar below the screen is covered with a fine metal mesh. Timeless without extravagance. In the middle a small white diode decorates and only decorates the front view of the B520. It is not bright enough to illuminate the keyboard. Also the back view is well designed. The plastic case is brushed and in grey color so that it pretends to be noble metal. But this it does this pretty good. A metal grid covers the opening on top of the case, a good solution for the heat from inside to rise up outside.
Actually the six speaker have a clear sound and really produce a surround sound for media content. BUT here you can not have such a good sound as with a full sound system with a sub-woofer. Some tones make the speaker clank. I tested every volume setting to avoid this but with dissonant tones the outer speaker keep clanking.
Until now this machine smoothly performs all my applications satisfactory. It also keep silent when running demanding processes. When playing games and the video card have its turn then i notice a little roar behind the monitor and actually the monitor keep the machine noise behind itself. I didn't run the newest PC games, thus i have no experience with higher demands. But i think with the mobile graphic card in this PC its performance will not be comparable with real desktop GPUs.
During simple use (i.e. browsing through the Internet) the temperature of the CPU moves between 30 - 40 degrees. Only ca. 1.5 GB memory of the available 8 GB are in use.
When playing video games the temperature of both the CPU and GPU growth up around 60 degrees. My maximum demand of memory didn't exceed 2 GB considerable. So i still have a surplus for future applications.
Because Windows 7 uses all four cores of the CPU at any time i didn't observe it to start the turbo mode of the "i5 2320" when using only 2 cores.
The only think to do better next time for Lenovo is to equip this PC with a better graphic card - think of ASUS. This AIO has a real desktop CPU and i think a mobile GPU could be bottleneck.
I'm very impressed of this all-in-one (AIO). I was looking for a year and compared nearly every AIO on the market. At the end i bought this one.
