1800 MHz I think but the video card thing is my problem. I dont think its CPU bottlenecked because when i play games CPU usage usually 50-70% rarely goes higher than 80% but the GPU just stay between 10-30% .I tested it with FurMark and the GPU was doing 62%-ish and then always spiked to 90-ish% so the graph was just spikes between 60-90%.
