I'm building a new pc and i noticed that some graphic cards (Winfast PX8800GT) are PCI-E 2.0, but on all new mobo's i just see PCI-E 16x. Should look for a mobo with PCI-E 2.0 or are they compitable with 1.0????

You aren't going to get much if any preformance for the most part so there is no reason to spend tremendous amounts of money on a PCI-E 2.0 motherboard.

They're not too expensive, I saw an ASUS PCIE 2.0 mobo for about $170AU odd.

PCI-E 2.0 is backwards compatible with PCI-E 16x.hacker_xyzzy

I may be wrong but I thought they were only backwards compatible with PCI-E 1.1, which you get on P35 mobos but not before?

Things are never going to be futureproof though-you can get a board with PCIE 2.0 support and then get caught out by DDR3 RAM sometime next year. If you get a board with both, by the time PCIE2 and DDR3 become necessary, we will need a new mobo for Nehalem at the end of 08/start of 09.
