short term upgrade suggestion

[Hsur]

Well I broke down and ordered a new monitor, but i think i put the cart before the horse by not upgrading my pc first. My current outdated system is a P4 2.0, 1 gig ram, 5700LE agp. I would like to upgrade to a PCI-e mobo and get a new video card while still being able to use my P4 2.0 cpu and DDR memory. So can someone recommend a decent pci-e mobo and video card that will get me by until the dx10/conroe stuff comes out?

Thanks in advance!
