Questions about a "Used" video card on Ebay.?

Could anyone give me their opinion on if I should buy BIOSTAR/ATI Radeon HD 5770 1GB DDR5 PCI-E Video Card

Its just within my price range and much better than my current video Card. My other question is, will it fit into the same slot as my Nvidia GeForce 8800GTS, and is it as slender as it, my current card slips right in and snaps in. Are all graphics cards made to be 'universal' to standard computers with their size and install ability's?

I upgraded from an old 320mb 8800GTS to a Radeon HD 5770 myself- it's a huge improvement, about 4X faster.



Really high-end cards are often physically longer, but most low-end cards only occupy 1 slot (in terms of width) while serious gaming cards usually cover the adjacent slot as well.
