Will a PCIe 3.0 x 16 gpu work in a PCIe 1.0 x 16 mobo slot. The Nvidia GeForce 8800 GT gpu I had quit. I need a gpu card comparable or better than the 8800 GT. I'm looking at a PNY GeForce GTX 750 TI video card. The computer I have is a Gateway FX7020. The mobo is an ECS MCP61PM-GM AM2 mATX powered by an AMD Phenom 9600 Quad-Core Processor with 4GB of memory, running 32-bit Vista. I gutted the original case and put everything in a new NZXT Source 210 case, for better air flow, and to accomodate a new 600-W Corsair PSU. Any advice would be appreciated.

contrary to what others have said, it is not fully backwards compatible. pcie1 slots provide less power, and some pcie3 cards may work on them while others don't get enough. Sometimes a bios update will fix this so check your motherboards bios update release notes.
