Like was said above, the video card is what will matter the most. Yes, Conroe gets better benchmarks, but the difference wont be that earth shattering in-game. If you really care about having the lowest superpi score, go Conroe. If you care about getting the most out of gaming, go with a dual core Athlon X2 or Opteron, and spend the extra money on a video card like the 7950GX2.
