is this a good agp graphics card?

i bought an nvidia geforce 6600 256mb agp today. i bought an ati radeon that was faulty off ebay last week. the core clock & memory clock was meant to be 412mhz & 375 respectively. 378 & 230 but when i went into the catalyst control panel it said it was only 378mhz & 230mhz.. why??? is there a way i can fix this? i cant even play games with it, as it goes black & cuts back to my desktop.(sometimes it stays black).. anyway, is the geforcs 6600 any good? will itr be able to play games like, fear, prey, & oblivion?? i dont really if it has to be low details etc, as im waiting on vista coming out then ill build a real gaaming pc... thanks

 

either the card is faulty or the drivers just arent right

if you have ati drivers still on your computer you better erase them and also get the latest drivers from nvidia

 

i got a 6600gt i can run bf2 at 1280*1024 with almost everything on high

 

can someone give me a link to the latest geforce drivers,my gpu is a 6800xt
