I've read several GT 740 vs. R7 250 threads, but the proposed solutions don't work in a slim Gateway box with limited PSU options.

Requirements are:
  • ■ Can't require more than 400 Watt PSU with 28A on a single 12V rail. (Prefer if it can run on a single 20A 12V rail if possible)
    ■ Must strictly occupy only one slot (including the fan... no fans sticking up)
    ■ Must be low profile and reasonably short.
I appear to be limited to either a Zotac GeForce GT 740 w/ 1GB GDDR5, or an XFX Radeon R7 250 with 2GB of DDR3. Which of these would be better/faster? And does anyone know of any better options?

Many thanks.
