Good value graphics card for those that want DirectX10 capabilities (with Vista) for the new generation of games coming along soon (e.g. S.T.A.L.K.E.R. 23 March).
If you're not convinced by DirectX10 + Vista just yet (e.g. drivers are not very efficient) then this card will provide excellent performance for DirectX9 games with XP.
This factory overclocked (hence OC in the title) outperforms the more expensive 8800GTS 640mb version.
