Well, I’d still go AMD dual core. You want to speed the encoding time up on DVD shrink, you need 4 things. First is a fast DVD ripper, a lot of the speed is the source drive. Second is a fast CPU, northwood intel chips are getting rare, prescott SUX, and AMD spanks the pants off either! So when they finally arrive, go for the bottom end AMD 64 dual core chip. It will improve multitasking IMMENSLY, and it won’t be much more $$$ than a single core chip of the same speed rating. No matter what you’re going to spend about the same $$$ on a mobo, and if you’re not going to use SLI, and some of the other stuff, you can save some $$$. The nVidia chipsets are starting to mature, and DDR ram is dirt cheap. If you go intel, you’ll either have to buy DDR2 or get a bastardized mobo based on a mixture of technologies that don’t belong together. Either way you go, if you don’t go PCI express, you’re hosing your upgradability. Third thing you need is memory bandwidth, which AMD’s integrated memory controller RULES for this. The fourth thing is a fast hard drive, you allready have sata drives. Getting them off the PCI bus will give them a LOT more throughput, so I’d say you’re set there. Honestly, A 32 bit CPU is a waste of money too, and the 64 bit intel dual core chips are EXTREMELY difficult to cool. They are overly hot power hogs, and I don’t think they’ll last long with all of the electron leakage they suffer. If you want to upgrade to something truly worth while, taht’s the way to go. My second choice would be an 875 chipset mobo and a NORTHWOOD 800 mhz bus CPU. That’s mature technology that is extremely reliable, and still very fast. It’s not going to be any cheaper than an AMD 64 system though!
