I have an old Dell Inspirion 530 machine (Q6600 core2quad, 3gb ram, pci-e 1.0 port) that I want to throw a sapphire HD 5850 into. I understand the HD 5850 is a pci-e 2.0 card. I will be upgrading the stock power supply to a Corsair CX-430 (430w 80+ supply).
Should I expect huge bottle necks running the card in a pci-e 1.0 port instead of the usual 2.0 port? Will it run only at half speed? Should I expect very bad gaming performance?
