Here we see the overclocked 4650 nearly tied with the standard Radeon 4670 in Crysis. The Sapphire 4550 also sees a slight bump with the increase in memory clockspeed. The 9500 GT fits somewhere in between the video card classes. As we can see the 4500 isn't quite able to handle DX10 medium settings on Crysis. It wouldn't be very playable at 18.5 fps but the 4600 cards don't have any problem.

Unreal Tournament 3 is much less of a graphics workhorse than Crysis and here we see all cards perform well. Again the 4600 cards are on top but we do see a slightly larger difference between the 4600 cards. Not bad though for the 4650.
