<< If you are specifically comparing the 32 MB GF2 GTS and the 64MB MX400, I can say from experience, the GTS is FAR faster..
It's well worth whatever the extra cost is, the MX400 cards are not a particularly good value in comparison to a GTS card with DDR SDRAM.
go DDR. >>
an mx is $82 @ newegg while a gts-v is $65, but i'm aiming for a gf2 ti500 64mb ddr so i can oc to a gf2 ultra
