Graphics card in sony vaio pcv-rx651

That graphics card is an AGP x4 graphics card. These are painfully old and can actually be costly to replace due to the old tech not really being made any more.

Regardless.. the following are all upgrades that your computer can take:

Hope this helps.

Thanks Acer. Based on what you've said and looking at new card prices, it would be more cost effective for me to buy a new box with Windows 7 on it and a card with enough memory that now is pretty much standard, i.e. at least 128 mb of memory.
