nvidia problems

Absolute newbie. Excuse for poor English. In short. After trying Ubuntu Studio 7,8,9,10 I have installed 64Studio 3.beta(64amd) and liked it.Realy rock solid app. At that time(or those times,or those time, do not know exactly) I had inside motherboard VGA card and all worked OK but Rosegarden graphic(it was slightly hanging up). So I purchased nvidia 9800 GT card (Linux driver version 190.53), to improve performance, and have now problems. Have read all topics(on my opinion), and not found out how to resolve the problem. I know, that there is no linux-headers-2.6.29-1-common-multimedia available to install naitive nvidia driver, but is there somewhat way out? Substitute it, (e.g) for nv driver to get better resolution (but I don't know, is it installed? how I can install it?and how I can get its options ) Send me, please, all teminal command about this item and I'll provide you all required information.
