Time For A Price Adjustment?
It has been almost one month since the release of NVIDIA's next generation GeForce 7800 GTX graphics card. Originally intended to be tagged at USS$649, by the time of the actual launch, it was adjusted downwards to US$599. A quick check online however showed that some cards are already available for as low as US$540. And mind you, these are full retail versions from well-known vendors, not bland OEM cards. Therefore, it comes as no surprise that there have been
rumors predicting a further price cut
to US$499 within the next few weeks.
Whether or not these rumors will eventually turn out to be accurate, there is no doubt that NVIDIA has been getting pretty good yields for its silicon, such that it is able to deliver the product in such quantities. With variations of the GeForce 7800 series poised for release soon, NVIDIA is probably planning to reduce prices in order to better position the GeForce 7800 GTX (whose value proposition is already pretty good). While those who have bought the GeForce 7800 GTX may be feeling a bit disgruntled about the 'devaluation' of their cards (which is part and parcel of being an early adopter), this can only mean great news for those still waiting to take the plunge.
Therefore, this is also the appropriate time for prospective buyers to start reading reviews about the GeForce 7800 GTX cards offered by the different vendors, so that they can make an informed decision on which card is the right one. Although, the first batches of GeForce 7800 GTX cards offered by the vendors are mostly repackaged cards from NVIDIA, there are some differences between them, mostly in terms of the bundle and the default clock speeds. Today, we intend to get to the bottom of the GeForce 7800 GTX from one of the major manufacturers: the Gigabyte GV-NX78X256V-B.
Here is Gigabyte's take on the GeForce 7800 GTX.
