Obviously a 9800NP/PRO/XT will own anything below it, regardless of VRAM, the only difference is bundles and clock speeds. For example, if you saw a 9800PRO for 150 bucks, you can bet it's the 128-BIT underclocked verson, whilst a 250 dollar 9800PRO might be overclocked/come with better cooling (this is assuming the regular ati 9800PRO costs 200 bucks, which it does not). If you're going with a 9800PRO, I STRONGLY suggest the HiS 9800PRO 128 meg version, worth all of the 240 bucks because you can overclock WAY past 9800XT speeds, and that's a damn good value.
