The i3 7100T isn't the greatest desktop CPU, but for light computing it will work for you. The only difference between it and the regular 7100 is the 7100T has a lower clock which means it runs cooler and uses less power. You lose about 0.5GHz over-wise everything else is the same. If the 7100T is all that you can choose it is sufficient.
On Passmark the 7100T is about 12% less powerful.
