The great thing about PC games and PC hardware is that when a game is released that really pushes the boundry on the visual front you can go back later and turn up the eye candy.
I remember when Far Cry was first released and the top card at the time was a 9800XT -I was limited to playing at either 1280 x1024 without AA or a lower res with 2xAA. The game used to drop to below 20fps and stutter in some jungle levels and fights.
Then a month after release the x800 pro cards appeared and suddenley Far Cry could be enjoyed at 1600x 1200 with a lttle AA.
The next updtae was thanks to Nvidia which allowed HDR!....and now I can have 1920x1200 Wide Screen, 16XAF, 4X AA, Max detail and HDR @7 which looks superb!
I am sure other releases like Morrowind Oblivion and the next Far Cry will follow the same pattern....thats why PC tweaking and upgrading is so rewarding IMO!
I for one have had my moneys worth out of Far Cry in the last two years!
