Im building a new gaming PC and I am torn between the GTX480 and the HD5870. Both machines are going to cost about the same to build ($20 difference). My CPU is going to be an AMD X4-965BE. I do plan on going either SLi or Crossfire and have selected a mobo and power supply that will support the additional GPU. My question for all you tech-savy folks is: if you had a choice and could afford either, which would you choose and why? It appears that as of now, the 480 is just better than the 5870. I just need a little more insight as to why I should choose one over the other. Thanks!
