Paanong versatility? In terms of gaming?
May noticeable improvement din ba sa PQ kung Radeon HD 6850?
Yes, versatility as in gaming and other consumer-oriented 3D tasks.
You get full post processing sa HD 6850, sa built-in mo you'd be utilizing adaptive post-processing (dependent on workload). Hindi lang nga deep color ang output Radeon 6850, since consumer graphics adapter siya. Saka scary din baka mahirapan na PSU mo sa 6850 at 15A lang 12V rail nyan. HD 6670 or V4900 malamang eksakto lang.
By the way, gamit mo na ba yung iOS remote ng PowerDVD?
