Leadtek Charges In With The G70

When NVIDIA mentioned that their latest flagship, the GeForce 7800 GTX, is available now from all their major vendors, they weren't just trying to smother you up. Unlike in the past where there were long pauses between official graphics card product launches and the actual hardware availability, NVIDIA this time round has worked really hard to ensure that's a bygone fact. Indeed by the launch date, there were already limited quantities of the GeForce 7800 GTX floating about. Within mere days of the launch, near full-scale availability was achieved. This is really an unparalleled move in recent times that has brought NVIDIA into the spotlight of their close partners (and consumers) for delivering a product that's not only made official, but can be bought the very same day. Seldom would you find such tightly knit launches in the electronics and IT world, but every now and then, they do take place and this time it was NVIDIA's turn to keep its promise.

The striking box packaging of the Leadtek WinFast PX7800 GTX TDH MyVIVO.

Leadtek was among the most renowned NVIDIA-only graphics card launch partners and they helped ensure NVIDIA's statements came true with their WinFast PX7800 GTX TDH MyVIVO. We were lucky to obtain a sample early enough for this full review that's just days after NVIDIA's launch and our full-blown coverage of the new GPU. If you happened to miss our NVIDIA GeForce 7800 GTX article, we highly recommend you to read that up here , which will get you up to date on quite a few matters pertaining graphics technology, direction and of course just how well the new GPU fares. For those of you who had your dose of GPU technology updates, we'll commence this review with the Leadtek card's technical specifications:-
