The second link doesnt work... but there's certainly one clear choice in the 200$ range... it's definately teh GTX460. You can spend $200 on a base model, $230 for a 1gb, or $250 for a 1gb superclock. Doesnt really matter.... they're all amazing cards for the price.
If you only use one normal monitor, the base model at $200 will be fine. If you run dual monitors and/or very high resolutions... scoop up the 1gb model.
