Dell Optiplex 790 SFF upgrade
Hello,
I am trying to build my own gaming desktop. It is my very first time building one so I am new to a lot of stuff. These are what I have right now: Dell Optiplex 790 sff, Samsung 8 GB ram, Kingston 480 SSD, Cool master 4o0 watts power supply, AMD Radeon HD 7570 low profile GPU, and i5 3230M CPU. Now, I am aware that the cpu I have will not fit into the socket, and that I need to buy a new one. Which cpu should I buy? Which ones are compatible? Also, is my desktop going to be a decent gaming desktop? Any advice would be appreciated.
Thanks!

CPU is totally un related to gaming performance. You cannot use a 75W video card. If you have USFF you cannot use any card at all because there are no slots.
GT1030 is the only model GPU that actually works.
Newer RX series video cards will not work due to requiring UEFI bios.
Low profile cards are required. Max out the Ram and use GT1030

As for video cards, I've had the MSI GTX 1050 TI 4GT Low Profile running in mine for about a year. Nothing else was touched to the stock Dell SFF 790. Wonderful little gaming pc.

Hi @speedstep,
Why is it thought that the CPU has nothing to do with gaming? The CPU sits idle as long as there's a GPU card?

Not supported doesn't always mean not working. Many 790 refurbs are sold with Win10.
Anybody that says certain Optiplex's can't be used for gaming should check out the "Optiplex gaming rig" videos on YouTube. A "Star Wars" version is one of my favorites.
Since Optiplex's are business class, there's already some power for gaming as compared to many home PC's. This is not to say Optiplex's are all out gaming rigs.
A list of CPU's are in the tech guide. Search by "processor."

Games are about the GPU more than the CPU.
Doesnt mean its not working just means INTEL Graphics is not known for gaming performance until you get into IRIS PRO that has dedicated ram for the GPU rather than stealing from system ram.

This is not a "gaming" PC. It was designed for business and is limited on power upgrades.
Suggest you reconsider with this model. It is a 2011 model and thus 8 year old technology. Dell does not support Win 10 on this model.
