I need a new graphics card! Iv got the nvida 6800GS and and the newer more complex games are starting to lag. I was thinking of upgrading to the 7 series like the 7900 but i heard that soon nvidia are releasing new modles or a new line of cards, is this true? and does any one have any info on them or any links to web sites containg info so i can have a look and decide weather or not to wait. Thanks
