Any body know if these blocks will fit or know of any other high quality vga water blocks that will?

there's a tradeoff when you watercool an sli system.
you have to use relativily low profile waterblocks so the top one doesn't hit the bottem video card - but going with a low profile waterblock often means you have to remove part/all of your ramsinks.
ive seen the mcp50 used pretty effectivly in an sli system. id just take some measurements and then look at the dimensions of the block ur interested - better to be safe than sorry

and get some good tubing because of the tight radius you'll need from one card to the next.
