INTRODUCTION
It's once again one of those special times of the year that all computer gaming and technical enthusiasts live for, new graphics solutions. Preceding every one of these tumultuous occasions there's always a certain amount of truth about the product(s) in question coupled with vast amounts of rumor, supposition and hype. We at Bjorn3D have been around for over ten years and have seen a number of these events come and go; some being obviously more memorable than others. Today marks the launch of what could be one of the most memorable of these occasions, NVIDIA's radically new 200 series of graphics solutions.
Bjorn3D will kick off our on-going coverage of this gala event with a detailed preview of the flagship of the line, the GeForce GTX 280 provided to us by XFX. For clarity's sake notice we said "on-going" and "preview". As with the debut of any new generation of graphical product there is almost always a portion of the manufacturer's final vision of that device that is either immature or incomplete, and the GTX 280 is certainly no exception to that premise. We fully intend to go into great detail in this preview about what's currently available and what you can expect in the future from the NVIDIA 200 series of graphical products. For sake of this introduction, suffice it to say the features available for today's product preview are a splash in the pan compared to what will be available shortly after this launch day. Thankfully all these missing features are software controlled and the final products are nearing release.
