Przecież masz podane osiągi mocy całego zestawu. Można sobie orientacyjnie przeliczyć. Ewentualnie porównać z poborem mocy swojego zestawu.

Testujący, czy to na benchmarku, czy innych vortalach zapominają o jednej podstawowej rzeczy. Mianowice: Każdy komputer kiedyś się starzeje, a przeciętny Kowalski połowy jego "środka" lub od razu całego nie wymieni, bo chciałby po...

I co z tego, skoro już w poprzedniej generacji były karty HD3870 z 16TMU(!!), które w wielu testach wyprzedzały 9600GT, a w niektórych nawet 8800GT - kartę teoretycznie wydajniejszą. AA akurat tu jest bez porównania, już wcześniej...
