Well what I'll say is that it's more powerful than the MX4000 you've already got, but it's about the cheapest you'll find a replacement for. You will be able to return it to scan if you have any problems, but I wouldn't expect you to need to.
how did you know which type to look for as this is what i was getting confused with there are so many different types just wondering if this would be ok and fit into my computer http://www.pcworld.co.uk/martprd/st...null&sm=null&tm=null&sku=006401&category_oid=
you're definitely looking for AGP, since that's what type of graphics card you already have. The 6200 I posted from Scan is about the cheapest AGP card you'll find new.
