So I just upgraded my G4 AGP 400 again from a Sonnet 800 card to a Powerlogix dual 1.2 based on the 7447 chip. I had originally ordered a dual 1.0 G4 based on the 7455 chip but it was backordered and I needed something quickly as I am in the middle of mixing a project for which I needed more power. The dual 1.0 upgrade had a 256k L2 cache and a 2MB L3 cache. The 1.2 that I ended up getting has a 512k L2 cache and no L3 cache. My question is this: would the dual 1.0 have given me significantly more power in Logic Pro due to the L3 cache than the dual 1.2 I am currently using. I am under the impression that the L3 cache can do a bit to alleviate the bottleneck of the 100mHz system bus on my G4 but is it something that i will really notice a difference in? I have a 30 day money back guarantee on this card and I am wondering if I should get the dual 1.0 that I originally wanted when it comes in. Thanks to anyone who has any insight into this matter.

The 512 l2 is going to give you an advantage over the 256 l2 cache right? So you would need to balance up the two...how about online performance tests, have you found any relating to your cpu models?
As you have an extra 20% clock speed over the dual 1.0 and double the l2 cache I would sit tight and count the blessings! -------------------- Simon Flinn
