Once you get connected online you will see the download process begin once you try starting the game with the desktop icon. You will prompted to first create a user account which is easy enough for logging onto their servers. You will only have to do this once unless you clean "cookies" off of your drive where you simply re-enter user name and password just like any other online account.
TigerDirect may have more cards available then newegg due to end of year clearance and low inventory at the moment. Plus holiday shopping drained the stock there somewhat. But newegg often sees a lower price and provides a little detailed info on various models. Are you looking at ATI or NVidia cards. I can take any of those and run them on a Radeon X1300 Pro with only 4 poxel pipelines at stock. And that's not a gaming card. Let's take a look at some other ATI under $300 at the first links and some NVidia on the others.
The top end ATI model X1950 Pro 256mb PCI-Express card is seen for $239.99 at

Don't bother looking for an ATI card at TigerDirect. Apparently they are stuck on XFX and EVGA models. Newegg is the one that offers a much wider selection and ATI as well as NVidia models. The next step is a look at the NVidia models seen at newegg. Two NVidia models stand out there with the eVGA 512mb 7950 GT PCI-E card running at $279,99 seen at

Asus, MSI, ATI, NVidia, eVGA, and BFG are the top contenders while brands like PNY and Foxconn... you know the rest there.
