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?

It will work but the performance will be reduced. Make sure you have a PCI-express 2.0 compatible motherboard to fully enjoy the 8800GTS's capabilities.

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.

It will work but the performance will be reduced by up to 7%. I wouldn't worry about that, but it's still better to get a mobo with PCI 2.0. Your next video card will be more powerful than the 8800GTS and will lose a lot more in a PCI-E 1 slot.

Yep. People get x38/48 for the higher fsb for ocing, not the pcie2.0. Graphics cards today aren't powerful enough to make old pcie1.1 a bottleneck. In a few years, it may change though.

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.

@OP: OK, let's compare the GA-P35-DS3L and the GA-X38-DS4 for example. The price difference is about $120. Paying that much more just for PCI-E 2.0 is not worth it IMO. But, on the other hand, the GA-EX38-DS4 gives you more SATA ports and two video card slots and RAID, i.e. it's much more future-proof. You also get FireWire, eSATA, more cables, etc. Consider all the features before you decide, OK?

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