Is that a question or are you telling us that its not worth? in any case everyone here knows that buying the low-mid end dx10 card doesnt seem to be worth right now but whoever has bought it just hopes that a future driver update may resolve things.
Low scores in initial DX10 games are to be expected. It'll take a while for the DX10 technology to meture and show returns.
Your better off getting a high end DX9 card then a mid/low range DX10 card.
Are these games just ill optimised or is it something else? The 8800GTX performing so horribly is bad news for guys like me, who have just bought one. Lets hope developers stick to DX9 for at least a year more, and here's to 50+fps in crysis...
