I just noticed that the price has fallen to $299 for the Intel Core 2 Quad Q6600 (2.4 GHz) processor at newegg. If you’re looking for the best system to run Paint.NET on right now, this is a great place to start! I’ve personally been using the Intel Core 2 Extreme QX6700 for my development system since December, and it’s awesome for those of us who are writing and optimizing multithreaded code. If you’re a developer then I highly recommend getting one.
P.S. I just finished up the integration of the DDS plugin for Paint.NET v3.10. And then I used OpenMP to optimize it for multiple threads: it is much faster on a dual- or quad-core system now! I’m still shooting to have a beta out by the end of the month.
