You've probably picked the best time to buy in about 2 years, especially if you are looking for deals but do thread carefully. As you probably know the next gen cards are about to launch in the next few weeks or have just started to come out such as the R9 285 which itself isn't all that amazing but it destroys the 750ti and even the GTX760 from 1st reports.
Both AMD and Nvidia have failed to get down from 28nm to 22 or 20 in 2014 meaning gains for the new cards out this christmas will be smaller than anticipated but thats good news. It means there will be many deals going on with the last gen cards there will be bargains to be had as the last gen gets sold off.
As an example AMD just dropped their price on their top end card the 295x2 (which I have waiting to go into a new build) from $1500 to $1000 so we can expect similar percentage cuts from both AMD and Nvidia on the 280, 280x, 290, 290x and GTX 7 series.
When do you need it for and are you going to run triples (3gb to 4gb Vram preferable so the 285 wouldn't be great)
