x1900xtx running in 2nd pci express slot

[invisi0n]

i can install the x1900xtx into my asus a8n-sli deluxe motherboard because the zalman northbride heatsink i fitted is stopping it from going in. i currently have the x1900xtx fitted into the second pci express slot will this affect the performance of the graphics card?

Make sure the board is set to "SLI" mode via the jumpers, since by default I believe the PCI-e slots are configured as 16 lanes/2 lanes (meaning you are only using 2 PCI-e lanes which can cause a performance hit). Changing to SLI mode will change the PCI-e to 8 lanes/8 lanes and performance should not be affected.
