i just got 8800gt and i noticed some issues. when i start my pc the noise is very loud until it shows the bios stuff and then very quiet.and second when i load a map to play crysis, at the begining it lags for 4-5 sec until it loads the gfx and then it plays perfect.

what is happening? does my 8800gt have problems or it's ok?my previously card was the 8800 gts 320 mb and i have never had this issues.which is better card ?my old or my new?

i think i am in last boss and my team tells me to use the TAC gun against the alien ship.So where is the TAC gun?i only have the

pistol,scar,gauss and missle launcer.where is the tac?

finaly which is the best?and are there big differences or not?i have the 8800 gts 320.
