Hi,just a word of warning. The nVidia 8800's GPU (G92 chip) appears to be the first PCI Express 2.0 chip. As such, some mainboards may have trouble booting up with this card inserted. Among these boards are Asrock 4Core Dual VSTA and Asrock 4 Core Dual SATA2.There is one glimmer of hope though: By applying a different Flash BIOS to the 8800 GT cards, the GPU can be configured to appear as PCI Express 1.x part and then the board will boot. These BIOSes are labelled "Gen1" BIOS, as opposed to "Gen2" BIOSes.The NiBiTor utility available from this site http://www.mvktech.net/ claims to be able to modify most 8800 GT BIOSes to Gen1. Also some manufacturers provide the Gen1 BIOS on request - some manufacturers assure they even continue to honor their warranty even after flashing.I am one of those affected and I will soon have to flash the BIOS. To do this you may have to set up a bootable USB stick (or floppy drive) with the nvFlash utility installed and the Gen1 BIOS as a binary file. The catch 22 is: I need to plug the card into a different PC because mine does not boot up with the card.There is some risk that a broken flash procedure will ruin the card, similarly to flashing your mainboard BIOS.Christian

I'll tell ya...I wouldn't even CONSIDER flashing my vid card BIOS unless I was under the protection of a Power Interrupt back-up module....Something to think about before you attempt it.Actually, I wouldn't want to flash anything unless you have a power-interrupt back up unit between the mains and the computer! One that will give you at least 10 to 15 minutes to complete and then shut the system down if a mains failure or spike should occur.Mitch

The BIOS flash procedure worked. The 8800GT now works in my crappy "el-cheapo" board from ASRock on 4 measly PCI-X lanes. DDR 1 RAM, Quad Q6600 processor. The system was a bargain ;-)I used an Asus 8800 GT Bios as the basis. Using NiBiTor I configured the same device and vendor IDs as in the original PNY 8800 GT graphics board. After making a backup of the original BIOS I flashed it using nvFlash from a bootable USB stick.Getting OK performance from FSX now even with most rendering options on "High". Still cannot enable bloom though.
