hi, the nvidea 8800gt graphics card on my dell xps420 has just died and i need to replace it. was just looking for one similar or a bit better, have a 375 watt psu and six wire plug in. can anyone recommend a new card i can just slot in with no additional mods. Tried an asus Nvidea gt 440 from Maplins but when i got home found it didnt have plug socket. guy said didnt need to plug in as had big fan, but i wasnt convinced so didnt buy.
