+2 More reasons against
Very Small Maximum On-Board Graphics Adapter Memory
At only 1.024 gigabytes, the ThinkCentre E73 has a quite small maximum on-board graphics adapter memory compared to most of the other few processor core PCs that have been around for around the same time as the ThinkCentre E73. The average maximum on-board graphics adapter memory of few processor core PCs that were released one year ago is 2GB.
5 Other reasons to consider the Lenovo ThinkCentre E73
Released Over a Year Ago
This desktop computer has been on the market for over a year.
Average Processor Clock Speed
With a processor clock speed of 3.5 gigahertz, the ThinkCentre E73 has a relatively standard processor clock speed compared to most of the other desktop computers that have been around for more than a year.
Alternative 3.5GHz processor clock speed desktop computers currently available that you might want to look at include because of it's better review score, the ProDesk 600 G1, or the ProDesk 400 G1 ($279.99) both from HP or the Asus BT1AD.
The ThinkCentre E73 has a fairly average hard drive capacity (500 gigabytes) compared to most of the other few processor core PCs that have been on the market for around the same time as the ThinkCentre E73.
We think you might also be interested in some of the other 500GB hard drive capacity desktop computers currently available including the Asus VivoPC VM42, the Lenovo H50, or the DELL OptiPlex 3020 ($299.99) which has better reviews.
Average Internal Memory
The ThinkCentre E73 has a relatively average internal memory (4 gigabytes) compared to most of the other few processor core PCs that are a similar age to the ThinkCentre E73.
We think you might also be interested in some of the alternative 4GB memory PCs currently available including the Revo One RL85, or the Revo One RL85 both from Acer or the Lenovo H50 which has better reviews.
If you would prefer a bigger internal memory then you might want to consider the DELL OptiPlex 3020 ($354.00) (8GB) which is also higher rated.
