Hi, I'm looking for some help seeing as I don't really understand much about this kind of stuff and so far every explanation about it has been way beyond my technical abilities. I'm running a so-so Windows XP computer, lots of storage space, only 256MB RAM, with a Geforce2 mx/mx 400, which apparently is an AGP 4X video card. A guy I know is selling a Radeon X1300pro 256MB DDR2 4X/8X videocard. What I'm interested in knowing is: 1. Can my system handle the new card? 2. Will I notice any significant graphics/speed difference if I were to upgrade, assuming my system only has an AGP4X compatible slot? What if it has an 8X slot? 3. What's the approximate value of a used Radeon card? 4. In your opinion, is it worth it to upgrade? Thanks in advance for your help, and please spare the criticisms about my crappy system and knowledge of it. I'm not made of money or time.
