Hello everyone, I had never posted on this site before, so first of all thanks in advance for any information you can provide 
You see, I'm planning on buying a new gaming PC, as the one I currently own is getting old. I am buying on a tight budget an, unfortunately, I have absolutely no idea about building a computer, so buying the pieces of a computer and assembling them together isn't an option.
Anyway, after looking extensively for cheap assembled computers, I have come down to two options that are within my budget and seem to be the most powerful. The only real difference between the two systems are the CPU and the GPU, as the rest of the assets are pretty much equal. So if you could advise me on this final decision, I would be really grateful.
Anyway, down to the issue, one computer has a Pentium G860 and a HD6770 graphic card, whilst the other has an AMD AM3 Athlon II X4-640 CPU and an Nvidia GFX 550 ti graphic card.
So, which one do you think will perform better on most modern games? I plan on playing games like Battlefield 3 or Skyrim on high settings (hopefully)...
