"In some new games, the GTX can be up to 80% faster than the GT"
Please state/link one gaming example benchmark where the GTX256 is 80% faster than a 7800GT at 1280x1024 and below .... (I doubt many are using 1600x1200 for a GT or GTX in the newest titles like FEAR or COD2 anyway)
Edit.... Ooops...! i followed your link, and you were indeed correct..I even saw an example where it was right at 100% faster, which I would not have expected..!
