-Base Clock Speed: PCIe 3.0 = 8. 0GHz, PCIe 2.0 = 5. 0GHz, PCIe 1.1 = 2. 5GHz
-Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
-Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
-Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s
Astea sunt diferentele intre slorurile de la placa video. Tu ai PCIe 2.0 si placa video are PCIe 3.0. Placa video va merge dar nu la capacitatea maxima. Uita-te la Data Rate. Este dubla la 3.0.
