Hey guys, what is the lowest-end CPU to run any GPU w/o any significant bottlenecks? For example, is the AMD Phenom II x3 720 BE able to run the hd5870 w/o any bottlenecks? What about the Amd Phenom II x2 550 BE? (I realize that the MoBo and the RAM also can be bottlenecks)
Its just that whenever I look at peoples custom configs, they always have a high end GPU paired with a high end CPU, for example the AMD Phenom II x4 955 BE with the hd4890. Is this necessary if gaming is the primary purpose?
What resolution are you running at? At 1024x768 there is no processor capable of running even a 4870 with no bottlenecks, and even the overclocked i7 used in the 5870 review encountered bottlenecks at a few resolutions. It all depends on the games you play and the resolutions you play at, if you are playing at high resolutions like 1920x1200 you need a high end GPU and it will be stressed enough that it wont be bottlenecked.
