Has anyone seen benchmark results for the new powerlogix, sonnet upgrade cards? I'm interested in seeing results comparing the dual to single cpus of course, but even benchmarks comparing the new 800mhz upgrades and the old sonnet duet cards would be great. Basically, any link that anyone has regarding the performance of these cards I would greatly appreciate. I'm getting quite sick of this 450mhz g4 and with the relatively close costs of the duet sonnet 500 cards and the new powerlogix 800 card... I'm trying to decide. Thanks for any suggestions or articles!
