If you're gaming on this, then the 6200 won't cut it. It'll do well on low settings in games, but other than that, you'll be stuck. You should get atleast a
Radeon X700Pro for decent gaming. However, the Geforce 6600GT is a very good card for gaming.
There is a thread on AMD Tech Forums about the second fastest drive to the Raptor. You should check it out. They recommend getting a Hitachi SATA 7200 PRM drive. They cost the same as the Raptor, but have 160GB and other higher capacities. However, when compared to a Raptor, installing Windows on a Raptor is only 2-3 minutes at max faster than the Hitachi. So, it would be a better buy to get the Hitachi.
