Motherboard compatibility with pci e 2.0
Hi everybody i have a ECS GF7050VT-M motherboard. I believe this motherboard is PCI E 1.0 bus and not 2.0. I plan to upgrade my old graphics card, a 8500gt to a gts 250, hd 4870, or hd 5770 which are all pci e 2.0 cards. I'm not sure would those cards work on my motherboard and if they do work, would there be any noticable drop in performane because the board is pci e 1.0 and the cards are pci e 2.0. My other specs include a dual core intel e7300 cpu, 4 gb of ram, 750 gb harddrive, and a 450w psu and soon to be a 585w. Thanks for the time.
The cards should work and performance will only be limited if the 2.0 gcard exceeds the 1.0 data rate.
"PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1. Overall, graphic cards or motherboards designed for v 2.0 will be able to work with the other being v 1.1 or v 1.0."
