Be wary of spending a lot of money on a 512Mb Graphics card. Current models do not have much, if any, advantage over cards with the same specs but only 256Mb memory.
Broadly speaking, the differences are undetectable by the human eye.

A tip for anybody thinking of buying a new home PC because a salesman has told them that theirs is 'out of date'.
No matter how old it is, if it does what you want it to do - it ain't out of date.
