How good is the 20" iMac's ATI Radeon HD 2400 XT?

[kabunaru]

I have a MacBook and yesterday I just bought an iMac (cheapest one) . I couldn't afford the other ones. Will the HD 2400 XT show improvement in games over GMA 950? Just how good is the HD 2400 XT card is?

Its a little bit slower than the X1600 in the old White iMacs. Much better than
the GMA950. Like 10X better.
