Hello, I am looking to upgrade my graphics card. I do not want to change my CPU. I would like to have the most powerfull graphics card (without bottleneck) the Phenom can handle when playing Battlefield 3 or F1 2011. CPU - Amd Phenom II 805 x4 2.5GHz Motherboard - Amd 780G PCI x16 500 watt power source
More aboutphenom 5ghz
a 6870 or 7850 gtx 560 i and 6950 is good choice by the way what ur budget
I'd say nothing faster than a 6870/GTX560 (non ti). Anything else will be severely bottlenecked by the processor.
