As a matter of editorial policy we do not include overclocked cards on general reviews. As a product, reference cards will continue to be produced for quite a while, with good products continuing on for years. Overclocked cards on the other hand come and go depending on market conditions, and even worse no two overclocked cards are alike. If we did normally include overclocked cards, our charts would be full of cards that are only different by 5MHz.
However with the 6800 launch NVIDIA is pushing the overclocked GTX 460 option far harder than we’ve seen them push overclocked cards in the past –we had an EVGA GTX 460 1GB FTW on our doorstep before we were even back from Los Angeles. Given how well the GTX 460 overclocks and how many heavily overclocked cards there are on the market, we believe there is at least some merit to NVIDIA’s arguments, so in this case we went ahead and included the EVGA card in our review. As a reference point it's clocked at 850Mhz and 4GHz memory versus 675MHz core and 3.6MHz memory for a stock GTX 460, giving it a massive 26% core overclock and a much more moderate 11% memory overclock.
However with that we’ll attach the biggest disclaimer we can that while we’re including the card, we don’t believe NVIDIA is taking the right action here. If they were serious about having a higher clocked GTX 460 on the market, then they need to make a new product, such as a GTX 461. Without NVIDIA establishing guidelines, these overclocked GTX 460 cards can vary in clockspeed, cooling, and ultimately performance by a very wide margin. In primary reviews such as these we’re interested in looking at cards that will be around for a while, and without an official product from NVIDIA there’s no guarantee any of these factory overclocked cards will still be around.
If nothing else, pushing overclocked cards makes for a messy situation for buyer. An official product provides a baseline of performance that buyers can see in reviews like ours and expect in any cards they buy. With overclocked cards, this is absent. Pushing factory overclocked cards may give NVIDIA a competitive product, but it’s being done in a way we can’t approve of.
