I have a dell 220 workstation that I got reconditioned. Unfortunately it only had 128 megs of rambus memory. It works fine, but the new release of RT seems to be bogging it down at times. Before I change brokers, I thought I should at least increase the RAM to something respectable and give it a shot. On the other hand, rambus memory is damn expensive, and this pc is nearly 3 years old. I'm wondering if I would be better off just getting a new one. Now I'm really wishing I bought two of the 4550's when dell had that incredible deal back in april. What do the experts out there say?
