My uncle is going to upgrade his processor to a dual core AMD and his looking to sell his Winchester 3500+. Right now I have a 3000+ with a 7900GT. My CPU is bottlenecking my system so I am looking for an upgrade as well. A few questions... 1. If I were to buy the 3500+ would it still bottleneck my system? 2. How much should I offer him for it? 3. Would it be a decent upgrade? Thank you in advance.
