There\'s budget, and then there\'s super-budget. (or "I don\'t care about performance.. just run my games")
Budget would be a Radeon 9600 or GFFX5700. If you couldn\'t spend more than $200 and you needed a solid card, either of these would do. Things like FX5600 and under and Radeon 9200 and under are old technology.
They market them as part of the same series, but they\'re in a different class altogether.
I\'m not sure who started it.. I think it was nVidia when they put out GF4MX\'s which were closer in performance to a GF2-GTS than a normal GF4..
