Hacked Drivers are only good for a limited amount of time. There is no guarantee that Nvidia won't modify them to eliminate the loophole, and new games come out all the time that require updated drivers. You should shop around for a used card for PhysX that way you won't be out of so much cash when it no longer works as planned.
I hoping Nvidia reverts from their decision, but yes when I actually have the money in hand to make the purchase, then Ill do intensive research, to see the pros and cons. Since unfortunately this industry is a little unpredictable sometimes, I can only make the real decision when I am actually going to purchase.
Who knows, by then maybe the lifted the driver ban, if not, Ill weigh out the options, and pick the best one. Physx is not a necessity, just a nice bonus, if it seems feasible at the time, but you suggestion is certainly valid. I merely choose the 285 more, because its easy to find water blocks for it, but if I can find a better alternative when I am actually purchasing the card, and a water block for said alternative, I will make the best choice .
Hopefully I will win the lotto by then though and not care . I still would, but I think you get my jist, hehehe.
