Nonu (666) writes "Adobe has officially released its Aperture killer, Lightroom, and the reviews are starting to pop up. Ars looks at Lightroom and concludes that it's a better choice for those without bleeding-edge hardware. 'Aperture's main drawback is still performance as it was designed for bleeding edge machines. On a quad Core 2 Duo Xeon, it is very usable but Lightroom just feels faster for everything regardless of hardware. Since Aperture relies on Core Image and a fast video card to do its adjustments (RAW decoding is done by the CPU), it's limited to what the single 3-D card can do. Lightroom does everything with the CPU and so it is likely to gain more speed as multicore systems get faster.'"
