Problems after installing new graphics card

Hello to all of the community! I just bought a new graphics card and came across many problems, therefore I came seeking help in this forum.

***My system specifications are in the end***

I was using Ati Radeon HD 4650, 512MB and wanted to buy a new and cheap video card, a little better than this one. I thought that Asus gt 610 http://www.asus.com/Graphics_Cards/GT610SL1GD3L/ was a good choice, since I couldn't afford much money at this time (I bought it for around 40 euros). The installation progress that I followed was this:

At first, I uninstalled the drivers of my former video card... Reboot

Next, I removed the old card and inserted the new one.

Turned on my pc and installed the new drivers... Reboot again

After that I updated my driver to the latest version, I rebooted for the last time and here's where the problems begun...  

The first problem is that my screen is slightly more blurry. I mean everything onscreen, which is irritating. I checked my resolution and it's the one I was using before (1680x1050) and also my refresh rate (60Hz). Also, on my google chrome UI, the buttons of minimize, restore, and close are red!? http://imageshack.us/photo/my-images/802/provlhma.jpg/

Next, are the games. I used to play skyrim with the ATI on low-mid settings and it was running smoothly. With this one, trying to play even on low settings becomes really painful  

But a thing that I saw that made me wonder, was this one: I have a blu-ray movie (FFVII Advent children) that used to lag at some parts with my old card, but with my new one, every last part of the movie runs amazingly smooth!

I will be grateful for your help, and please someone explain to me why the movie runs great and skyrim doesn't



My computer consists of:

Motherboard: Gigabyte GA-EP31-DS3L
