I’ve finally gotten around to building a new box.
My old was an AMD Athlon 2200+, with 512MB ram and a couple of 120Gb Drive. Still up to most tasks, but getting a bit hard driven in some cases.
New one is build around an Intel Duo 2 Core E6320 (running 1.86Ghz), with 2Gb ram and a 400Gb Samsung hard drive. I’ve mainly build it to be silent, but it can be over clocked if I so choose (an Asus P5B motherboard helps with that). I tried running it at nearly 3Ghz for at bit, but haven’t tested it extensively.
LightRoom 1.0: Export 16, Dng files to Jpeg. 10MP.
New: 47 seconds (33 seconds overclocked)
Old: 345 seconds
Yes, the SSE2 instruction set is really important for LightRoom and makes all the difference.
