Started using my new PC, but I think I'm going to stick with my 670 for awhile, see what happens with Maxwell.
I've got a question though, the overclocked cards you buy (most notably the Evga cards), are you literally just paying more because the 'Classified' has a better factory overclock than the 'Superclock' for example.

I think the best example are these:

Inno3D GeForce GTX 780Ti iChill OC at £559.99

Inno3D GeForce GTX 780Ti iChill DHS at £619.99

Would you literally just be paying an extra £60, because it has been factory overclocked, or is there more to it? Would it be difficult to achieve the same speeds with the cheaper version? Better heatsink? Better fans?

Mostly, yes, you're just paying for the exact same card with a different speed.

Sometimes manufacturers "bin" the faster cards, so a premium card would have a higher max OC than a normal one on average.

In a few cases (MSI Lighting or EVGA classified cards, for example), they actually use a better, more expensive PCB with the same chip. In other words, the GPU has better power circuity backing it up, which in theory gives you a more robust graphics card than can overclock higher.

You should never really choose cards by their stock clock speed. It's better to research each card individually, check reviews etc. because it varies from card to card.

For example, some EVGA SC cards use the standard PCB and just come factory overclocked while others come with upgraded power delivery. Then you have the FTW and Classified cards which have even beefier power delivery.
