Radeon Mobility HD 2400 XT (256MB DirectX 10 PCI Express x16)would compare in speed to a 8500gt on a desktop.. (i keep an 8500 in my living room pc.. it plays movies well but id never game with it)

a quick look at the benchmarks show this card will never play any dx10 game....

the good news is you dont have an integrated card.. so you can pull that one out... put it on ebay... and get something else...
