Hehe, well they "relatively" cheap! They've even dredged up an old Ti 4200 from somewhere or other. for anyone who's sick of their MX400 or whatever, a £60 vanilla 6800 or a £55 6600GT could be considered a worthwhile upgrade.
Cybermaxx-- I was having problems with google earth, and error messages stating that my graphics card was not suitable. Not into gaming or high graphics wants, so what would you recommend!.
Would mention that I bought a secondhand ATI Radeon 7000/VE/Dual Display/ AGP Video Graphics card a short while ago, but not having much knowledge on these things, haven't installed it as yet. Do you know of any comparisons against this card the cards in the link you have supplied!.
