I havent build a PC before this will be my first. the main games I wanted to play were BF3, Skyrim, and minecraft on at least Low or maybe medium since i have a low budget. I saw this article http://www.pcper.com/news/Graphics-Cards/Video-Perspect... and i think i am going to go with the AMD build which is
So i see on the video that it can run BF3 on low settings since it has a integraded HD 6550 and I am ok with that. My question would be if I wanted to upgrade in the future, could I upgrade the PSU and throw on a graphics card ( i was looking at the GTX 560 ti ) or would I need to upgrade the motherboard too, in which case I might not even bother going with this low cost build. Also is that processor worth it?
