hello all....just need a bit of advice about which GFX card to go for....i have the 19" Asus PW191 widescreen monitor which has a optimal res of 1440x900 ...so what i was wondering is it worth me buying the 8800GTX or because i can`t go any higher than 1440x900 should i go for the 8800GTS.....any help would be appreciated....cheers
