upgrading a Dell optiplex 775 computer system

[0123adtu]

I'm looking to upgrade my Dell Optiplex 755 computer system;
The CPU
Graphics and Sound Card
SSD
RAM
Im not sure which components will be compatible with the operating system i have upgraded to which is windows 10 and the use is for product design projects?

You're better off just replacing the whole damn thing, the 755 is far too old to be upgraded!

Which Dell OptiPlex 755 model do you have? The Mini Tower Computer (MT) or the Desktop Computer (DT) or the Small Form Factor Computer (SFF) or the Ultra Small Form Factor Computer (USFF)?

If you're going to be replacing that many components then it's not even worthwhile upgrading that obsolete BTX form factor system.

I wouldn't waste the money honestly. It uses such old technology you'd be better off putting that money toward literally any current gen system and it would outperform it by a good deal. If you can even find the DDR2 RAM or CPU, it'll cost more than its worth. To upgrade to a decent video card will require a new PSU, and that assuming your form factor allows a full sized card or PSU to be installed. You could get a sound card but really why bother, unless you're doing audio production, any onboard sound from a current gen motherboard will give you what you need. Really only SSD is viable since you can move that over to a new system.

The upgrades are for a project i have been assigned to and i have a new computer system which provides the same functions however im looking to evaluate how the upgrades i implement will compare to my current computer system.

Pretty easy to compare performance in terms of CPU changes, but if you have specialized software you'll need to test it yourself. You might be able to upgrade to Win 10, but the GPU might not have proper drivers that will allow a decent comparison. Everything else should be fine

I'm new to understanding how each component provides me an efficient upgrade and im looking to understand how using an old computer system like the Dell computer and providing that i apply upgrades how will the upgrades improve in efficiency.?

Now that is something entirely different than performance improvements!

If you get a totally new computer, you can find out idle and peak load power by visiting review sites like this one (dell already provides it for their system in the back of the manual). Test as I stated above, and then you can get a rough estimate of saved electricity. If you need a more exact measurement, you'll need a measuring device at the wall for both systems
