Quite Slow Processor Clock Speed
The average processor clock speed of comparable spec desktop computers that are a similar age to the OptiPlex 3040 is 3.1GHz, and the processor clock speeds range from 1.3GHz to 4GHz. With a processor clock speed of only 2.5 gigahertz, the OptiPlex 3040 has one of the slower processor clock speeds amongst personal computers of this age.
There are a number of other 2.5GHz processor clock speed PCs currently available that you might want to look at including the HP 400 G2[plb_3746914_price] which is cheaper.
If this computer processor clock speed is not fast enough for you then you might also want to consider the 400 G3 MT[pl_3817115_price] (3.2GHz), the 600 G2[pl_3816863_price] (3.2GHz), or the 400 G3 SFF[pl_3864883_price] (3.2GHz) all from HP.
Very Small Internal Memory
Latest PCs have internal memory of between 2GB and 32GB, and the average internal memory is 7.9GB. At only 4 gigabytes, the OptiPlex 3040 has a quite small internal memory compared to most of the other medium processor core personal computers that were released around the same time as the OptiPlex 3040.
We think you might also be interested in some of the other 4GB memory personal computers currently available including cheaper PCs such as the HP 400 G2[plb_3746914_price].
If this personal computer internal memory is not big enough for you then you might want to consider the HP 600 G2[plb_3816863_price] (8GB).
Very Small Hard Drive Capacity
The OptiPlex 3040 has a quite small hard drive capacity (only 500 gigabytes) compared to most of the other medium processor core personal computers that have been on the market for a similar time to the OptiPlex 3040. Recently released medium processor core personal computers have hard drive capacity of between 250GB and 3TB.
Computers with a bigger hard drive capacity that might also be worth considering include the HP 400 G3 MT[plb_3810816_price] (1TB).
+8 More reasons against
