Hey HD 5850 would be an excellent choice for that resolution
While the HD5850 would be a good choice (I have one and I REALLY like it), your 9800 GTX will also suffice under most circumstances. You may not be able to max out graphics and maintain acceptable frame rates, but with the proper tweaking for your games settings, it can do the job.
