They should work just fine. PCIe gen1/2/3 slots will work just fine with gen1/2/3 cards, the speed will just be limited to the slower of the two parts. Kinda like plugging an USB2 device into an older 1.1 port. It'll work but will be slower. >From personal experience working with a mix of Gen1 & Gen2 devices & slots in high end workstations/servers, you won't really notice the performance hit of running a gen2 Video Card in a gen1 slot unless you play the latest 3D games or run some really high end 3D apps. Only place I really noticed performance differences was in running higher end RAID cards & NICs. Some can max a gen2 x8 slot and running on a gen1 you can see the performance hit. But I digress. ;-) -- Drew "This started out as a hobby and spun horribly out of control." -Unknown
