will radion hd 6870 get bottle necked by a AMD phenom II x4?

So im looking at getting the:
XFX Black Edition HD-687A-ZDBC Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

I'm just wondering if it'll get bottlenecked by the:
AMD Phenom II X4 980 Black Edition Deneb 3.7GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Desktop Processor HDZ980FBGMBOX

Or will the CPU be bottlenecked by the GPU? Are there any other factors I should worry about such as the RAM or motherboard that could cause bottle necking?

Also, while I'm at it, is this a good combination of a CPU and GPU? Any suggestions or advice would be great.
