Eww. Nvidia's FX series sucked, plus you can get better cards from both Nvidia and ATI for cheaper than that first one.
Yes agp cards are still sold the best one you can get is the 3850, but thats a overkill for most pcs that still have a agp port.
2 options. Get a crap card that works, or get a new PC. No point getting a high end AGP because it sounds like your PC is old enough for you to need a new one in the coming months. And then your expensive AGP is useless :p
lol am i dreaming? 15 $? this might be pretty cheap but the shipping is 20$ i dont think there isnt such oldschool Graphics card in store in Estonia
i had a 3.00 gHz p4 512mb, and a nvidia card that was aweome 3 years ago (cant remeber the number) and getting more than 30 fps (low dets) was a true miracle , so i cant really understand how are you not having fps issues.
