Just wondered if anyone had any advice on how to improve the processing power of my PC. I've got a fairly high-spec PC built around a Shuttle frame. It includes a P4 3.0Ghz processor and 1GB of fairly fast RAM. I recently added a top end graphics card (Geoforce 7900GT with 256MB ram). I don't know how fast my hard disk is but it is a fairly decent Maxtor 160GB unit. Anyway, I've never been too impressed with the processing speed when using Photoshop CS2 and now with the new Lightroom Beta 4 it is pretty poor. Question is: can I improve what I've got, either by tweaking the system configuration or changing some of the components. I'd have expected a 3GHz unit with 1GB ram plus the graphics card I've got to be pretty decent. Any views would be helpful (other than get a Mac 'cos I can't right now!).
