Hi, I am considering buying one of those high-end video cards( probably 4870X2 or 4850x2) sometime around christmas. My question is whether the today's latest high-end card will support my Intel Dp965Lt mobo which has a pci express 1.0 slot? Even if they support, will I face any problem running them on a PCI express 1.0 slot?

PCIE 2.0 video cards are perfectly compatible with PC!E 1.0 MBs. I use 9800GT and 9600GT on my two 965s.

badge is right, I just did some Crossfire testing uses 4870's on an old 975x motherboard.

"Q6: Will PCIe 3.0 products be compatible with existing PCIe 1.x and PCIe 2.0 products?
A6: PCI-SIG is proud of its long heritage of developing compatible architectures, and its members have consistently produced compatible and interoperable products. In keeping with this tradition, PCIe 3.0 will be fully compatible with prior generations of this technology, from software to clocking architecture to mechanical interfaces. That is to say PCIe 1.x and 2.0 cards will seamlessly plug into PCIe 3.0-capable slots and operate at their highest performance levels. Similarly, all PCIe 3.0 cards will plug into PCIe 1.x- and PCIe 2.0-capable slots and operate at the highest performance levels supported by those configurations."

Thanks for the help guys. I have choosen to buy the 4870 card but one thing that bothers me is that the psu that I use is not certified by ATI. So will I face any problem in the future for not using an ati certified psu?

An ati certified psu will have the correct connectors and enough amperage on the +12 volt rail. If you have that coverd, you have no worrys. The PCIe 2.0 standard is 5 G/s .The P965 chipsets PCIe has a 8 G/s path ,this chipset was way ahead of its time. Your PCIe 2.0 video card will operate at the PCIe 2.0 performance level.
