So I need a new graphics card and I'm really stuck at choosing one. At first, I found the Nvidia one but then I was told that the radeon one would be better as it runs cooler (my current nvidia one is overheating)
Here are the links:

I keep finding pros and cons for both card, therefore it's really hard for me to choose.
I'm not much of a gamer apart from the occasional period of playing Sims 3 or Portal 2.. Also I'm now waiting for the new Saints Row IV (another reason why i need a new card)

Also I don't even know if they're compatible so here are my specs:
Microsoft Windows 7 Home Premium
Version
6.1.7601 Service Pack 1 Build 7601
System Model HPE-490uk
System Type x64-based PC
Processor Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz, 2934 Mhz, 4 Core(s), 8 Logical Processor(s)
Graphics card NVIDIA GeForce GT 230
