Dear Friend :
I suggest you buy Top 3 VGA brand manufacture in Taiwan, because price is resonable and Service is good.
Here's the ranking of VGA (Base on total shipment)
No.1 MSI (微星)
No.2 ASUS (華碩)
No.3 Leadtek (麗台)

in my idea is, basically NVIDIA solution are base on same design, so the hardware feature is almost the same, price is the top concern,
conclusion is I recommend MSI MX400 solution !!
Good Day Antonio
