i tried AudiGrabber, too, but...it's not my thing...My fav is Easy-CDDa, it's a bit more comfortably, with lots of other Features, but....only trial....
soo, i think, you should take the 5200, it's just better than the ATI 9000 (or the others), i think, and i could play some good Games with the 5200, too, but not on the highest preferences... With a little overclocking, i could play HL² pretty good...But I would buy a worse PC and a better Graphic card.....
