I've been using TT for over a year and I've been very happy with it. My HTPC is running 1.2 and its nigh on bulletproof stability wise. I've resisted upgrading to 1.5 until recently to maintain stability (if it ain't broke don't fix it right). However now I'd like the multidrive capability so I've already bought and downloaded the upgrade. My spec is Asus tusl2-c mobo Radeon VE 32M audiophile 2496 pioneer slot loaded barracuda 40Gb ata100 W2K (sp3 avoided sp4). I want my upgrade to go nice and smoothly and above all retain the superb stability I've got with my machine. I'd rather stay at 1.2 than lose stability to be honest. I believe I need the following drivers for my kit to give maximum stability with 1.5. cat 2.3 for the graphics card maudio October beta for the soundcard the 1.5.46 patch for TT after the upgrade. I have downloaded these fellas already. Am I good to go?
