Well yes, that's a given with SLI, or Crossfire for that matter also, though CrossFire is a bit more forgiving on the identical card thing (and SLI too now, you no longer need the same brand, and small clock differences will go to the lowest clocked card to match up. Memory must be the same amount for SLI though).
The problem with Quad SLI is that spliting the screen up into four sections, or alternate frame scissor, or quad alternate frame just are not very efficent. Basically it throws out the other two cards because your CPU gets bottlenecked around having to calculate all of that (its done in the drivers, the CPUs arena).
As for DirectX 10: That means you MUST upgrade to Vista, that means you MUST buy a DirectX 10 video, and that means you MUST spend a lot of money for next to no gain early on. Personally, Dx10 is a breath of fresh air that DirectX really needs. But the entry point to it is going to be expensive.
