A little under 2 years ago i asked the same question and was told the Nvidia 6600GT was where it was at. I managed to get a good deal on a 256mb one for a little over 30 quid last year. The new need for speed is out in november, so i think it's time for an upgrade. What should i be looking at now?

The upgrade is likely to include a new system to go with it, so the previous stipulation of AGP is no longer important. Although i'm still not going to spend silly money on it.
