So, what is the deal with PCIE anyways?

I will be building myself a new computer early next year, and thus have been looking at different processors, motherboards, video cards, etc.......

I looked at a review for the ATI X700 and am happy with its performance vs. its price. I noticed that it is a PCIE and have read a little bit on it. I am just wondering what exactly this technology is and why I should get a motherboard with PCIE instead of AGP.

Much faster transfer speed than AGP. PCI-E video card slots will do 16x (dual slots for SLI will do 8x each). Plus PCI-E is a direct, point-to-point connection.

Wow, you can go old school SLI? Reminds me of the days of the voodoo 2......

SLI is coming back. nVidia has it available now, but ATi will have a comparable solution soon.

There is no noticeable difference in speed between agp4x 8x and PCI-E. The only exception is if you buy a board that supports SLI and run 2 PCI-E cards.

Benchmarks between the cards are pretty much identical.

I would not bother with PCI-E yet, unless you intend to get a board that supports SLI so you can buy a second card later on down the road to speed your graphics up, Or you've got the bucks to go SLI right off the bat.
