More G80 features abound

As if we mere mortals needed more reasons to be excited about G80, here are a couple more tidbits: 128-bit high dynamic-range and antialiasing with 16X sampling.

The high dynamic-range (HDR) engine found in GeForce 7950 and Radeon series graphics cards is technically a 64-bit rendering.  This new HDR approach comes from a file format developed by Industrial Light and Magic (the LucasFilm guys).  In a nutshell, we will have 128-bit floating point HDR as soon as applications adopt code to use it. OpenEXR's features include:
  • Higher dynamic range and color precision than existing 8- and 10-bit image file formats.
  • Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions.
  • Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain.
  • Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications.
NVIDIA already has 16X AA available for SLI applications.  The GeForce 8800 will be the first card to feature 16X AA on a single GPU.  Previous generations of GeForce cards have only been able to support 8X antialiasing in single-card configurations.

This new 16X AA and 128-bit HDR will be part of another new engine, similar in spirit to PureVideo and the Quantum Effects engines also featured on G80.

Why does it not surprise me your from Texas?

First off.........$100 is not the majority part of $500. If you were to run your 500W system 24hrs a day your bill would be $36/mo (assuming .10/KWh). Not to mention the fact that you computer should go into standby mode, and under normal operating circumstances is taking less than 200W.

Even more power hungry would be the 2 CRT monitors. Although I'm sure that they also go into standby mode and consume less energy. Go LCD, but don't expect to save more than $5/mo for getting LCD's and a new energy efficient computer. Your dis-illusioning yourself if you think you'll get better gains.

The primary factors in an energy bill are always;
1. Air Conditioning/Heat Pump
2. Hot water heater (electric)
3. Clothes dryer (electric)
4. Oven/rangetop
and if your like my household.........too much 1500W hair dryer use.

To reduce your bill, invest (<--notice I did not say spend) for a new 16-18 SEER/12 HSPF heat pump (I'm assuming HP since that's Texas) and really save that $100/mo.

With reguards to the Nvidia card, I'm dissapointed that it takes so much power.

If that's a swipe at Texans or their intelligence, or maybe lack thereof, perhaps you should use YOU'RE, instead of your.

Why does every post that tries to combat the whiny "my computer gets hot!" posts get voted to oblivion? Admittedly, the swipe at Texans wasn't smart, but the rest of the post was worthy.

I run my X2 @ 2.6ghz system, 600w Seasonic S-12, which has the standard components, a pump for the water cooling loop, and an LCD (all fed through a UPS which probably introduces minor inefficiency) 24-7 and the impact on my Florida bill is actually quite negligible. And when I say 24-7, I mean full CPU load 24-7, non-stop. (Recently before a reboot after 29 days of up time, had 6 hours of idle time noted in task manager). And yet, a few months ago, the system was dead for a month, about 3wks of it, while I fooled with a busted motherboard. Did I notice a drop in my light bill? Nope.

Therefore, will anyone that can afford such a monster of a video card notice a significant swing in their bills? Very much doubt it..

It's a concern for laptops and SFF for energy drain and heat respectively, but for desktops? Give me a break.

Read more carefully. He never stated his computer caused $100 of his bill. He mentioned buying a new computer and SHAVING off $100 of his bill. Whether his statements are accurate is moot. My point is you should read and comprehend before you start criticizing people's posts.
