Why would anybody buy a prebuilt computer? Well, even though the modern market today has allowed us to get the components and build a computer by ourselves, there are reasons why some people still prefer to buy a prebuilt computer. Prebuilt computers, particularly the ones produced by big names, certainly have undergone and passed various tests that ensure the quality. For the sake of constant reliability and consistent performance, a prebuilt computer is often a safe solution. Now, Dell has released two compact and portable desktop models, Dell Optiplex 755 and Dell Optiplex 780. Which one should you choose?
Design
Dell Optiplex is a line of compact and portable desktop computer models that is very popular on the market, especially for government, corporate, and education uses. Each of Dell Optiplex 755 and Dell Optiplex 780 is available in four variants: mini tower, desktop, small form factor, and ultra small form factor. However, the ultra small form factor variant usually has some minor drawback, such as Dell Optiplex 755 USFF that only has two DIMM slots and supports 4GB maximum memory, and Dell Optiplex 780 USFF that has two DIMM slots and supports 8GB maximum memory. The other variants of Dell Optiplex 755 allow for 8GB maximum RAM, while Dell Optiplex 780 allows for up to 16GB RAM. In addition, Dell Optiplex 755 only comes with 7 USB 2.0 ports, whereas Dell Optiplex 780 features 8 USB 2.0 ports. Having more USB ports is always handy and beneficial, as it will allow you to connect more peripherals or external devices.

Performance
Dell Optiplex 780 has received subtle yet very beneficial upgrades from Dell Optiplex 755. Both models still come with 800/1066/1333 MHz FSB. However, Dell Optiplex 755 supports only DDR2 RAM. Dell Optiplex 780 now supports DDR3 RAM, which is quite significantly faster and more powerful. Furthermore, Dell Optiplex 780 is coming with a newer Intel Q45 Express chipset, as opposed to Dell Optiplex 755’s Intel Q35 Express chipset. The performance difference between these two chipsets is relatively marginal, but, still, the newer model is better. Last but not least, Dell Optiplex 780 has added the support for Intel Pentium Dual Core processors for improved processing speed from the previous Intel Core 2 Duo, Quad, and Celeron.
