what's the frequency of the gpu?
there are few different.
and that silly 15fps proof...doesn't prove anything, its unplayable that way.
And i'm sure you wont have the 1450mhz on ur one, as its i3, not i5.
dont get me wrong, im just saying that you shouldnt expect that it can run such things decently.
check these benchmarks:

also note the resolution, i doubt you will be using 1024x789.
PS: dont think you expect to use gta IV, but intel gpus are not supported
