After buying a NVIDIA GeForce 8800 GT graphics card, found that it wasn't compatible with PCI Express 1.0, it is only backwards compatible to PCI Express 1.1. There is a way of flashing the cards BIOS to make it a compatible, but that seems a bit tricky.
I have no idea who told you that, but the only issue that is know is with mainboard having a VIA chipset which isn't following the PCI Express specifications to the letter causing PCI Express compatibility issues when you put in certain PCI Express 2.0 graphics cards. Now this issue could not be fixed by VIA so NVIDIA did some analysis and came up with newer BIOS's that fix this, and their cards are actually fully backwards compatible.
Secondly there isn't anything tricky about flashing a GeForce 8800 GT with the newer BIOS to get it working fine on these annoying VIA based mainboards. So which card do you have, like manufacturer and can you backup the original BIOS and attach it on this thread so we can check it out? And, no the Radeon HD 3870 should work just fine ATI had already anticipated the VIA chipsets with their cards. But the Radoen HD 3870 is slower and will soon get replaced by the Radeon HD 4870 series.
