My resolution is 1680 by 1050. Would the HD5770 be a whole lot better than the HD5670? or will it only make a small difference? I'd like to play Warhammer 40k: Dawn of war 2 and it requires A 128MB Video Card (Shader Model 3) - Nvidia GeForce 6600 GT / ATI X1600, or equivalent. And I'd also like to play AVP which requires DirectX 9.0c compliant video card with 128 MB RAM (NVIDIA 6600 or better, ATI X1600 or better). Would the HD5670 be able to handle them both with no problem? I'd like to run the game on medium at least but I'd really like to run it on high. I've got one PCI-express slot and one PCI slot and my current card is integrated. If if you could tell me which card would be good that'll help me a bit. Kinda confusing.
