Re: HIS H567Q1GD Radeon HD 5670 IceQ for my build
In terms of DX9 and DX10 capable power, the 4850 would eat up the 5670. If you're looking for DX11 support the 5670 is your only option. However, that DX11 support will only get you so far with a weak, DX11 enabled GPU such as the 5670 (which is a mid-low end GPU). I would personally go with a 4850 over the 5670, and keep a stronger DX9/DX10 performance.
