sorry i didnt see that.. its just to give you the idea of price and what one. Like we said before they are pretty much all the same. If you want one now or pretty soon its gonna be tough.. cos theyre selling like hotcakes!! everyone is buying them. you cant really go wrong with any 8800GT.. im from uk so i dont know how exactly newegg restocks.
Optical drive is DVD drive/burner. You cant really go to wrong here either just usually get a popular one.. i chose that liteon cos i have one and its also popular. ive had no problems. for $6-7 its got lightscribe feature so might aswell i think, if you like some dvds labelled nice, but remember youll need special lightscribe dvds for that, they burn normal ones aswell so dont worry.
at the lower resolution both cards perform pretty much the same. at higher resolution 1920x1200 (usually 24" monitor) 512mb outperforms the 256mb version.
