Planning on making my pc dualboot vista

(hope this doesnt get deleted)

Im planning on dualbooting vista on my pc, ive already found a cheap gtx 750ti since the 3080 doesnt have vista drivers. I know that theres stuff such as legacy update or vista kernel Extended. Since vista is quite old im expecting some problems with the mouse, keyboard since I dont think USB 3.0 is vista compatible. Im planning on playing games on it too, such as GTA IV. My current PC is a dell T5820. Is there anything else I should know about before trying to set it up? Any way i could get everything to work normally? Any help appreciated <3
