編號係GV-R929OC-4GD REV:1.0，係gigabyte OC版R9 290唔係普通版290，亦唔係290X，4GB VRAM，三風扇，注意普通機箱未必放得落。已簡單清塵。十幾年卡算幾新淨（2013 initial release）

8+6插電，冇run furmark，run左vcore顯核stress test（呢個test唔包顯存vram），正常。睇CPU-X同system-monitoring-center，見唔到有異常。PCIe 3.0 x16

三個風扇全部自然流暢轉動，除非full load，否則算靜。full load會比較響。DVI out x2，DP HDMI各1，共4 output，測試左1個HDMI同1個DVI，正常輸出。另1個DVI同DP未得閒試。淨卡一張冇綫冇盒冇單冇塵膠塞，已過保，只保證正常運作

差唔多有4060 5060 1/2性能，9070XT 1/3性能，7900XTX 1/4性能，當然比較食電。略低于480 580，略高于470 570 580 2048SP

TDP：275 W
Suggested PSU：600 W。不過我用我個CMPSU-550VX corsair 550watts火牛都正常run到，長時間full load都冇問題
