Taxes, Code, and Hardware

We got all of our tax forms today so now I can start doing those. I love this time of the year! I usually get to do my taxes, reregister my car, and have a birthday all in the same week. I'll be turning 28...still young right?

I updated my DE classes to give them a more logical hierarchy. They are much more manageable now. I'm also continuing my complete reading of the dx sdk docs. I am realizing that some of the newer aspects of directx such as HDR lighting are not compatible with my current GPU thus I am considering updating. I've been using nVidia cards forever but I am considering trying ATI. Does anyone know why one would be better than the other at this point?
