Look at this guys. A new card without the need of external power connecter.
This is a 4830, which SHOULD have 640 shaders. But, when i was reading it, i noticed it havig 800(same as 4850,4870,4890). Performs well. If u can get it in india and u dont have a PSU with a 6pin PCIE connecter,then this 1 is made for u. For benchmarks, follow this link:
