Now, the thing is I have an Nvidia 8400GS... And as you people know it's pretty old now, so I want to buy a 260GTX but the thing is... it says Pci-Express 2.0 x16... I have a Pci-express x16 but I'm not sure if it's a 2.0... Please need your help I'm attaching the nvidia control panel photo Thanks in advance! Please tell me if i would be able to install a 260GTX
You will be fine with a GTX 260. It does appear to just be PCIe 1.0 if you need that information for future reference. There is more bandwidth in the second revision (2.0) but a GTX 260 shouldn't saturate the PCIe 1.0 lane, so you wouldn't lose any performance.
