I am looking to upgrade my GPU on Optiplex 790 SFF, 3.1GHZ Core i5 - 2400
What are my graphics card options, combing though the threads did not give me a definitive answer
if any of you have done such an upgrade please shed some light
Save your money and put it towards your next computer. The obsolete SFF 790 does not support any worthwhile video upgrade--case is too small and it has a tiny, under powered power supply. Use it as is until you can replace the computer.
Its a pretty slim choice of cards, It will need to be something low profile, and something that doesn't need external power. If you want something cheap for higher resolution or multiple displays maybe a card like this.
Or if you are looking at gaming, something like this should do the trick for entry level gaming!
Hope this helps.
There is only 1 card I recommend.
