So I've been looking for upgrade graphics cards to play WoW amazingly. I was going to get the Geforce GTX 750 ti but it was not in stock at my local best buy, so i went with the best one that they had which was a Geforce GT 740, thinking that even though it is not a 750 it would still be good graphics. Long story short: i got home, installed it, opened up WoW, and the graphics are exactly the same as my old card. Maybe I can change some settings somewhere or something? Any help is greatly appreciated and hopefully I didn't just waste $120 on a noob buy!
p.s. my old card was a Geforce GTX 550
Holy Cow, $120 is a lot more than what you should pay for a 740.

DO NOT BUY COMPONENTS AT BOX STORES. They are almost always very highly marked up and often sell old stuff at new prices.
The GTX 550 you had is actually FASTER than the 740. For WOW the 550 will run it at top settings just fine. Return the 740 if you can, sorry to say, but you spent money to make your computer slower or at best the same.
You won't get better graphics just by swapping a card, you may get a better frame rate but to change how the game looks you need to actually change the game video settings.
Plus how well the video card can work depends on the CPU and RAM as well, not to mention for online games the internet connection also has a part.
