Doom 3 and Quake 4 Performance
We ran tests with both Doom 3 as well as Quake 4, and while the numbers aren't identical, the trends are similar. Quake 4 disables some of the graphical effects during the time demo, so I know that in real gameplay with audio enabled, your frame rates will be significantly lower than what we're showing here.
Doom 3:
Quake 4:
At low resolutions, performance once again scales linearly with processor speed. We still see large gaps across the board... until we enable 4xAA. At 1280x1024 and 1600x1200, antialiasing reduces the performance gap to less than 10%. Unless you're running SLI with high-end graphics cards, you won't need the world's fastest processor to get the most out of Doom 3 and Quake 4.

Neermind.. read this in the closing thoughts:"There is one other point to mention on the memory: overclocking with four 512MB DIMMs was almost a complete failure on the setup that we used. Other motherboards, or perhaps a BIOS update for this motherboard, might improve the results, but for now we would recommend caution with such attempts. If you want to run 2GB of RAM, two 1GB DIMMs would be a much better choice."
Good info.

Actually, switching supply efficiencies can change dramatically with load; I wouldn't count on the draw at the wall as a good indicator of system load change. The efficiency may change from, say 70% at half-load to 85% at 3/4 load, which, on a 400 watt supply, would show up as: 285.7 watts draw (lower power) and 352.9 watts draw (high power). Now, the system is drawing 50% more power, while the meter is only showing 23.5% more power draw.Something to keep in mind anyway as I don't know exactly what the difference in efficiency for that particular supply is....

It would be nice to know. However, if it's like the 470w one, it is 'close enough' at all loads.http://www.silentpcreview.com/article173-page4.htm...">http://www.silentpcreview.com/article173-page4.htm...

Yeah, from 2-400W it's pretty close. Nevermind me then. :)WRXSTI - Wednesday, December 21, 2005 - link
I cannot wait to get a 64 X2 chip! Maybe by next year is better...Futurebobis - Thursday, December 1, 2022 - link
