..well, at least Karlos understands the importance of adding RTG to an a1200 system. I guess if you just want to play games the ppc+bvision is overkill. And yes, OS4 is personal preference.
RTG was absolutely the biggest and the most significant upgrade to classic Amiga's usability when you're using it as main computer or mostly for the apps instead of games. I went the CV64/3D route with my A1200 (and later Mediator) and it was definitely bigger improvement than any CPU expansion etc (I went up to 060, not that it wouldn't been a big leap, but still nothing to compare what RTG gave).
But nowadays my RTG usage has moved to next generation Amigas, which are way faster than any expanded classic Amiga.. so.. today I think 060 is more important for classics than RTG
