I'm about to put in an order for a new PC... and wonder about the right Photoshop upgrade path. I've been using CS on an old W2K Pentium 4 system. I can (a) continue with CS while waiting for CS4; (b) grab PSE6 while waiting for CS4; or (c) upgrade to CS3 and forget about CS4. I'm a pure hobbyist and I have a lot to learn, about both photography and PP, but I'm willing to work at it. What would you recommend for me, and why? Thanks!
