After thinking for a long time, I have come to the conclusion that the Source engine is going to be used for a long time, and DOOM 3 will fall by the wayside. So in a way, despite the PS 3.0 support, buying nVidia is NOT future proofing your card, since a Radeon will run more games in the future way better than a GeForce. nVidia may choose to resolve this in their next release, but for right now, there is no one "future-proofed" card. Which makes pulling the trigger on one or the other nigh-impossible.
