Was hoping to get some advice on this, I'm aware I shouldn't need a dedicated physx card as the 670 should handle it. However I was considering getting one as I found Alice Madness returns was unplayable with it. I'm aware Alice is rather poorly coded but it was unplayable even with Physx on low. What I wanted to know was, is there a card out there that won't bottleneck the 670? (that isn't so pricey I should just Sli 2 670's) I've had a good look online, but haven't found any definite answers. I've been considering a gtx 460 768mb or a gts 450 I know these should comfortably handle any physx requirements but do not know if it would just hinder the 670. Any advice would be massively appreciated as I'm going in circles, my apologies if the answer to this is hidden in the forums. I did look I promise!
