Will a motherboard with PCI Express x16 work with a video card that has PCI Express 2.0 x16?

The current computer I have is a Powerspec 8500.

Quick Specs:

Intel Pentium D 820 2.8ghz dual core processor

Intel D945GTP motherboard (PCI Express x16)

250GB SATA 7200 RPM Samsung hard drive

1GB composed of 2- 512MB DDR2/533 DIMMS for memory

52x CD-ROM Drive

16x Dual Layer DVD±R/±RW Drive



I am looking to purchase a new one and hopefully be able to run a few games on it.



I am aware that PCI Express 2.0 x16 simply increases the data rate to 500 MB/s but will a PCI Express 2.0 x16 work with a PCI Express x16 slot?



Thankyou for your help.|||PCIe 2.0 is fully backwards compatible with PCIe 1.1. It works the other way around also, if you have a pci x16 1.0 card, it will work in a PCIe 2.0 slot. Only difference is the bus speed so the PCIe 2.0 card in the PCIe 1.1 slot will be slightly bottle-necked. However, with the current cards out today you will not really notice a significant change in performance.|||From Wikipedia:



PCIe 2.0 is backward compatible with PCIe 1.1 as a physical interface slot and from within software, so older cards will still be able to work in machines fitted with PCIe 2.0.





You are most likely using a PCIE1.1 slot, so it should be fine.
