OK! So yea I figured out the different versions you had posted (those are the actual Nvidia drivers).
But, still don't know the modded version you speak of?
I guess since I just bought a Nvidia card (ASUS gtx 550ti) that I found this thread interesting and if I got another card. I was more curious of what will work with what I have now. Of course I would be looking for a better one then I have now.
I didn't know that Nvidia cards were so "incompatible" with each other (former ATI is why).
And yes I am a noob to Nvidia cards
Thanks
