PCI Express 2.0 Question

I have a question regarding the PCI Express 2.0 x16 interface. I searched this forum, but all I found was part of the answer I seek.

My mobo only has PCI Express x16 slot. Most of the 8800GTS cards are PCI Express 2.0 x16.

My first question was Will the card work in a mob that doesn't have 2.0 slot? and several threads here already answer that yes, it will.

My second question was What am I giving up (performance wise) by not having a mobo with a 2.0 slot?

yes there backward compatible so u can use a 8800gts on a pcie x16. I dont see y u would use pcie 2.0 its bandwidth advantage is barely being used with a 8800gts, but if ur looking for a new mobo try finding one with pcie 2.0 if not a pcie x16 is more then enough. pcie 2.0 r a little expensive just get a x16 and spend more money on a better graphic card rather spend more money on a pcie 2.0.

PCIe is not expensive at all. And it offers twice the bandwidth.

exactly just save the 100 or use it on a better graphic card or i have a better idea use it for gas money. dam its for 4$ a gal!!

If you have an SLi setup that gets limited to 1.1 8x per slot, you MIGHT see some bottlenecking. If you intend to only run a single card, PCI-E 1.1 will do just fine for the foreseeable future.

Faster fsb is the main reason. Everything else is secondary.
