The next week me and my friend traded for a GTS 450 and flashing stopped, Nvidia control panel was easily figured out, and I OC'd that thing to a GHz.
That is why I choose Nvidia.
Okay when you bought your card yes the drivers were horrible and buggy but since then they have corrected all of that. Not to mention the new CCC is pretty snazy. Not only are the 5770's great overclockers they were cheap and scaled well in CF. I still have two CF'd 5770's both run an overclock 1000/core 1400/mem. I understand not all are equal but you can't just lay a blanket statement that yours sucked so all Radeons suck. You can not base a whole brand of cards based on your experience. I have owned both Nvidia and AMD and both have strengths and weaknesses. I am currently running both in my rig right now AMD for rendering and Nvidia for physx.
@OP If you want physx without having to buy two cards go with Nvidia. If you want similar performance with the ability for multi monitors then go with the Radeon. In all honesty you probably won't notice a huge difference in either card 570/6970 because most of the tests I have seen are only about 5%-12% difference in different games.
In the old days ATI and eventually AMD had really buggy drivers but that hasn't beent the case as of late. It also used to be that Nvidia ran really hot and were power hungry but as of late that is not the case. In fact the 570(from the tests I have seen) actually uses less power. If it helps though If you are more familiar with Nvidia stay with them. You will not be gaining much if anything by switching from Nvidia at this time.
@Rawfood As I understand it that doesn't have a lot of impact on the actual overclocking just the actual bandwidth you can theroretically get out of the chips themselves. It's like taking the ocean and pushing through a small canal. No matter how much you push you can only get so much flow and at some point you reach the diminishing returns. Thats where the more you push the less you get.
