Stalker Clear Sky is a pretty typical graphics workload for a modern game, and the GV-567OC-1GI is ill-equipped to handle this level of graphic detail. The Radeon HD 4770 is a better buy in this price range.

Crysis 1.2 - DX10	Source: Electronic Arts

Crysis is a science fiction first-person shooter developed by Crytek. Crysis uses Microsoft's new API, DirectX 10 for graphics rendering, and includes the new engine—the CryEngine 2—that is the successor to Far Cry's CryEngine. CryEngine 2 is among the first engines to use the DirectX 10 framework of Windows Vista, but can also run using DirectX 9, both on Vista and Windows XP.

At medium resolution in Crysis the GV-567OC-1GI is a little bit slower than the Radeon HD 4830, and the Radeon HD 4770 beats it easily. NVIDIA also doesn't have much difficulty outdoing the GV-567OC-1GI, even the Geforce GTS 250 manages better scores in Crysis.
