Are we talking about GAMING?
If gaming, what's the REST of the system?
- CPU
- System RAM amount
- 32 or 64-bit Windows?
- power supply?
Also, for GAMING there's a huge difference in how demanding games are. A game like WITCHER 3 is completely different from Torchlight and may require 5X the graphical power for max settings or more.
1GB VRAM?
There's no cut and dry answer but if 2GB is in your budget such as a GTX750Ti 2GB card then I'd get that. Unless you have 32-bit Windows otherwise get 1GB.
*The "a little more than you need" comment is completely misinformed. I could show you lots of GAMES that run below 60FPS with the GTX750Ti at 1440x900.
Summary:
Just not enough info to answer, not even whether you're gaming or not.
My PICK without knowing all the facts is this card:

(and the R7-250 is the crappiest card for value last time I checked. look up some benchmarks.)
