Re: GF 4 vs FX 5200
Even if it WAS the 64-bit version, it's going to be faster than an MX440. Not MUCH, mind you, but it will be faster.
Also, keep in mind the MX440 has NO shader support and NO multi-sample antialiasing - it's just a very, very overclocked GeForce2. The FX5200 will have up to shader 2.0 support (and, believe it or not, there ARE some games it can use it in - Tribes: Vengeance, and Pacific Fighters are two I have firsthand experience with on a FX 5200), and will have the notably faster (and better looking) multi-sample antialiasing.
