A:AnswerAbsolutely it can as this is my streaming pc. But a lot has to do with the specs needed for the game you're trying to stream. OBS/Streamlabs can take a good bit of cpu/gpu (sometimes as much as 30%) so running a 4k game 120fps could push most of its power. But this computer handles streaming encoding and decoding, internal capture card (from game pc), room lighting system and 11 other programs I run during streams with no problem.
A:AnswerAegis R 12TC-267US is basically the same specs with the exception that the graphics card is 12gb. Check the MSI website which lists all the different versions. that version is not available at best buy, though.
A:AnswerPlease note that the game suggests using at least a GTX 1070 equivalent. The Aegis R 12TC-443US will meet the minimum requirements to support this title.
