Well.. assuming you want to do some gaming, the best bang for the buck are the 7770, 270, 270x cards.. basicy the ones with a "7" as the 2nd digit. Otherwise that card is Ok.. you may just want to find a more modern one at a support standpoint.
3rd vote here for the Logitech G930, I use this for both work and gaming. One of the best headsets I have ever owned... and the best wireless one. Crazy good range too if you need to wander away from the PC for a snack.
