Pencil modding = using a pencil to etch an additional circuit. Used to make some dual-PCI-E boards SLI back in the day... also used on some graphics cards.
It is faster, its 5-10% faster, but its just as fast as a 9800GTX Superclocked, but the 9800GTX+ has a 55nm die over the 65nm (I think?) of the original 9800GTX
Yeah, does that help with cooling or does it up the power/ability of the card? I know the 45nm intels are better than the 65nm ones, but i dont know much more than that lol
Not exactly, depends on how good the core is, just because its smaller it doesn't necessarily mean its better. It just means its going to be less power hog and have lower temps
