Which of theese is the best gaming desktop?
None are terribly awesome gaming machines but Desktop 1 comes the closest, it just needs a better graphics card than the HD4670. That card is okay but it will struggle with more recent titles and you’ll definitely not be able to take advantage of your 1920×1080 resolution during gaming. Also if you’re going with Desktop 1, make sure to check what its power supply unit is. The “Quiet Xilence 480W” power supply unit on Desktop 2 and Desktop 3 aren’t very good ones either. The two 12v rails are only 15A and 16A, which basically just means you won’t have much ability to upgrade your graphics card in the future without changing your power supply unit. Hope this helps.
