While that are certainly old now, my 7800 GTXes weren't when I bought them and there still isn't any measurable offloading (of video en-/de-/re-/trans-coding) to them. You can tell you aren't using mesa-glx though. :) >> That's regardless of the CPU you use. >> There's still much transcoding involved.

Ron is right though. Unless you have a specific application that is 100%-ing your CPU, you probably aren't going to experience a measurable speed-up when moving to 64-bits. In fact, you might be better off using a 64-bit kernel and 32-bit userland since the kernel can save values in the extra registers for the inevitable return from userspace. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
