So, what about do some gaming and feel whether you get high performance or not.
Or you can install this one(GPU-Z):http://www.techpowerup.com/gpuz/
If it stated your card as 5800 series and the specs are right then you should not worry about what Furmark says...
Hi, Thanks for the reply.
I downloaded and ran GPU-Z and the results showed I was running 5800 series with the right specifications, however furmark, oblivion and fallout 3 all state that my graphics adapter is the 5400 series. Does anybody else have the same results?
