I can now report back on my GTX560Ti experience - wish to hell I had saved the %500+ it cost me.
After my last graphics card experience where "anybody with half a brain can install them, all you do is push them in" and it ended up costing me $2000 when I damaged the MB and of course the tech had moved on and I needed then a new processor, MB and ram

I decided to leave it to the experts...
So after paying a deposit for them to order me the card and the $115 min labour charge and then needing up upgrade the power supply from the 400w I had to 500w, I managed to pick up all of about 7fps ! This card should chew this and not break a sweat, yet I can only get about 10fps at medium settings with TSX enabled and unfortunately, trying to swap back to RW2 legacy mode still only brings about 10 fps, yet I could get 20+ with my old GT8600 card. The tech people kept it for an extra day trying to work out just why, tweaking and probing etc and in the end put it down to "faulty developer code" There should be no reason some users can get great results on a lower spec rig and yet others with newer higher spec rigs are struggling with playability.
At this stage, it is unplayable, so I have pulled the plug on the whole thing, awaiting acknowledgement from RSC that they are working on a solution, but I am not holding my breathe. There is no way I would even consider a system upgrade as I am likely to drop another $1500 or so and the chance is there it still wont run.

ps: as the saying goes, this is my individual experience and your mileage may vary
