Hello, I have a Dell Optiplex 745 (Small Form Factor/SFF) computer  and I was wondering if I could get any help on upgrading my CPU.

Currently, I'm using Intel® Pentium® 4 CPU 3.20GHz, 1 Core. It is x64-based PC. I would like to do some gaming on this computer. 

Therefore, I will need a decent processor.


A lot of people would say 'check your motherboard name and search the compatibility with the processor you want to get'. Unfortunately, it doesn't say or I have no idea how to find the name/number of my motherboard. I have attached a screenshot of the System Information, Summary and I hope it will help out a little.


Can I please get a list of compatible CPUs for my motherboard. (A website where it lists all of them, A list of worth mentioning budget CPUs or recommendation of the budget CPU or tell me if Intel i3 Processor would be compatible with my motherboard.)

The fastest CPUs you can put in an OptiPlex 745 are early (Conroe) core 2 duos (& quads??), (you would need a 755 or 760 for the later core 2 processors such a the E8400 or Q9550). It has an LGA775 socket motherboard so completely unsuitable for any i3 processor.


The SFF OptiPlex's are very restricted for space & have low rated power supplies, so you are very limited in your choice of potential graphics card upgrades. The integrated Intel graphics are not good for gaming.


Overall there is no hope of playing modern games with that computer.

IMO...there are a lot of refurb systems that outstrip what you have and are what I consider "good buys" that you may want to consider.  Be sure to note whether they are SFF or not.  The PSUs will probably be the weak link in all of these systems because OEMs just do not seem to go above basic power requirements when they build for the masses.
