Just throwing some info out there in case is impacts future purchase decisions.
It seems apparent from WMD Portal (pCARS) posts that while nVidia have been awesome at providing resources and assistance in making the game run great on their cards/SDK/whatever... AMD/ATi have been a lot more quiet. This means at present that nVidia cards are way-outperforming similar ATi cards. Of course the game devs are working to address this, but they obviously aren't receiving the same support. So just keep in mind numbers/tech specs aren't everything.
Wherever possible, find a benchmark chart that uses a game you're interested in (or at least a game from the same racing genre). Don't rely on benchmark programs/demo's as it's often possible for nVidia/ATi to 'cheat' some of the tests improving the over score, and some tests may not be relevant to racing games.
btw I spent some time researching the latest parts and providing some options to someone for a gaming/home theatre PC build at various price points to handle the latest titles. Would be a shame not to share it with the rest of you, even if it needs tweaking for your needs:

Note this person already had a case for the parts, you may need to add this as a cost. Don't forget things like keyboard, mouse, monitor, speakers, network, Windows, MS Office, etc, etc. If you want to go even cheaper then your best bet is either a pre-built system with one or two less-than-optimal components or second hand. You may find last-gen high-end graphics cards cheap on GumBay as well.
