How can this happen ??? The nvdia 7900 cards are faster than Radeon 9800 pro so how can the weaker 9800 pro have better graphics than the more powerful 7950gt?? Anyway i am pretty sure that my 8800gt has better image quality than a 9800 pro!!
Can you post some screenhots of games running with a ati card and some others screenhots of games running with nvdia card so we can make a comparission??
