Final thoughts, HEXUS.awards and HEXUS.right2reply
If you want the fastest single (default-clocked) graphics card in town, one that can paint the prettiest pixels (DX10) and run games smoothly at insane resolutions, look no further than the NVIDIA GeForce 8800 Ultra 768MiB SKU.
Think of it as a GeForce 8800 GTX OC Edition and you won't be far wrong. NVIDIA's massaged out any kinks in the G80 manufacturing process and released a model that is, on average, around 12 per cent fastest in most card-limited scenarios, thanks to the use of a faster core (612MHz) higher-clocked shaders (1500MHz) and faster memory (2160MHz).
What's pleasing is that NVIDIA's been able to accomplish this performance leap without sacrificing the GTX's quietness and, going hand in hand, by keeping power requirements (according to NVIDIA and not HEXUS' testing) at similar levels whilst increasing clocks. Overclocking, too, was impressive, and we expect partners to launch super-clocked Ultras featuring 650MHz+ core speeds.
The NVIDIA GeForce 8800 Ultra, then, is a drop-in performance upgrade for any PCIe-based motherboard, and will provide even better performance when coupled with another on an nForce SLI-supporting platform.
There are, however, a couple of obstacles in recommending the GeForce 8800 Ultra outright. The first is price. NVIDIA and its partners will charge close to £500 for a single Ultra. That's at least a £100 price premium over the already-expensive GeForce 8800 GTX, so whilst performance improves by just over 10 per cent, price is raised by over 20 per cent. That's what the Ultra's low HEXUS.bang4buck metric, on the previous page, demonstrates. Secondly, there are a number of overclocked GeForce 8800 GTXs already available that offer similar performance, for less money.
The high single-card price automatically brings other multi-GPU setups into play. Would it be better, in performance terms, to invest in two GeForce 8800 GTS 640 or Radeon X1950 XTX cards rather in a single Ultra? Perhaps, and we'll find out in due course. Lastly, AMD's Radeon riposte is close at hand, and any enthusiast owes it to themselves to wait and see what kind of performance/price the range-topping HD 2900 XT arrives at. Stock is due to arrive in the channel by May 15th. That'll be an important day for all concerned.
Bottom line: The NVIDIA GeForce 8800 Ultra 768MiB is the fastest single graphics card SKU on the planet and should make for the speediest multi-GPU setup, too. The question of whether it's worth the near-£500 outlay can only fully be answered in the next few weeks.
