if you have a 486 i recommend http://abcresellers.com/store/product105.html
very cheap for the rareness!!!
Ignore this. Its either a scam or joke-- not sure which.
Does "protable" mean portable? If so there is a great deal of variation, but Asus has some laptops with ATI 5 series cards. Since you cant buy graphics cards independently of laptops you should just be shopping for a gaming laptop.
Give us a price range and location/retailer and I would be glad to help.
