Help with Graphic card purchase

Hello all ! I'm looking to purchase a mid ranged graphics card for the barebone kit i just bought online. I'm looking for this card to run WoW at maxed settings without any fps issues, also d3 when it's out without too many problems. Im trying to set my budget at around $200 because i also need to purchase a new psu come christmas time. So far I'm looking at a 3870, 9800gtx cards, the 4850 is up there also for me, seeing how near xmas the price should drop...anyways should there be any other cards i should be looking at ? Thanks in advance !

Setup atm:

amd 9500 phenom quad core
2400xt -- being replaced
bestec 400w psu -- being replaced
3gigs 667 mhz
650SE
win vista 32bit premium

Care to name one?

To the op, the 4850 is the best sub $200 card out there. You should be able to find some around $150, unless you don't live in the USA. The 9800GTX isn't a bad choice either, though the 4850 is newer.

WoW isn't graphics intensive at all and, from the looks of it, D3 will not be either. You can actually settle for a much cheaper 9600 GT and still run max settings on a 17" screen.

Thanks a lot for the replies guys. Seeing how I'm going to be gaming on my 17" for a bit at the standard (1280x1024) and playing mainly the games i have listed, I'm going to go for the 9800gtx. Iv'e actually always wanted to give that card a try, seeing how I have always purchased ati cards in the past. This card should do pretty good if i chose to play the odd fps games here and there.
