Use Triple Buffering to make up for it.
Bloom and V-Sync don't do squat to make it look realistic. Bloom makes things glow unrealistically, V-Sync adds nothing to the graphics and only adds in a delay to mouse aiming, HBSO/SSAO deal with shadows so it's pointless to have on if I remove shadows, and I remove shadows as it makes character's silhouette stand out more. Again, nothing to do with perfomance.
You said, "7970 or gtx 680" and never mentioned SLI, 2, two, couple, many, multiple, or anything of that sort. I have it quoted in an un-edited post earlier if you want to check.
Tried it in many games. In first person shooters, I can still notice it. In single player shooters or non-shooter games, I'll have V-Sync on and with triple buffering. Same for all the other effects; on for single player. For multiplayer in something like BF3, I have the settings on in such a way that I ensure a high, consistant frame rate without making it harder for me to do well. Things like render distance must always be at max but things like shadows and vegitation/flora (as it's called in PlanetSide 2) have to be off.
