Hello everyone. I have a custom built computer. Its showing its age. It's a AMD Athlon XP 1800 at 1.53ghz 20 gig hard drive 768mb of ram and a TNT2 32mb video card. How much of a speed improvement would I see if I bought the entry level mini? I am needing to work on photoshop quite a bit - nothing too intense but would need more power than this pc can handle. Other than that I do nothing but web browsing, music, and email. Is the mac mini right for me or should I hold off and build another custom PC?
