That card will be MORE than enough for your resolution. You will likely be able to max out settings on just about any game you might care to play with that low of a resolution, so long as the game actually still has support for that resolution. I can say that a lot of games are going to look terrible and will probably be mostly unplayable at that resolution since the majority these days are designed for a 1080p minimum, but you'll have to decide that.
Even at 1080p though, if you were to upgrade your display, you should do fairly well with that GPU so long as you have reasonable expectations.
Thanks for the answer.
