Yeah maybe offering that many different products at such close speeds is confusing for the consumer.
X800 = 400/700 clock speeds 12 pipelines => think of it as replacement for X700XT (which replaced 9800Pro/XT) - this card is a direct competitor to 6600GT/6800nu. However, it only comes with 128mb of ram for $199 US MSRP, and 256mb card costs $249. However, it's availability is questionable. Only comes in PCIe. If you already have a 9800Pro, this isnt worth of an upgrade. Now add to that a higher price for PCIe boards and this whole "need to upgrade to PCIe ASAP" isn't necessarily going to save money due to extended upgrade path (but you'll end up paying $50 more for a motherboard, $100 more for the videocard).
X800Pro = 475/900 => 12 pixel pipelines - supposed to compete with 6800GT but right now costs more than a 6800GT and loses to it. Comes in PCIe and AGP but it's worthless considering 6800GT.
X800XL => 400/1000 replacement to X800Pro => 16 pipelines, it pretty much matches 6800GT (i'd say 5-10% slower), but it only comes in PCIe, making it an impossible upgrade for AGP crowd at least for now. It's also overpriced by $100+ over MSRP making it a bad deal.
X800XT = 500/1000 with 16 pipelines => basically starting with this card and cards below, this is faster than 6800Ultra. It can be had for $450US making it a "bargain" compared to X800XTPE/X850XTPE given that it's only slower by 10-15%. These cards can be found with 1.6ns memory (ie. Sapphire), making it essentially a X800XT PE given the 20mhz overclock on the GPu is guarantted and GDDR3 can easily gain 100mhz more.
X800XT PE = 520/1120 with 16 pipes => as you can see same as above but 20mhz faster core (4%) and 120mhz faster memory (12%). It costs roughly $520 making it simply bragging rights over X800XT.
X850XT => 520/1080 with 16 pipes => so falls between x800xt and x800xt pe. only comes in PCIe.
X850XT PE => 540/1180 with 16 pipes => top of the range.
One major disadvantage for PCIe users right now is that 6800GT PCI is around $440 and X800XL is $420 when X800XT AGP beats them both and can be head for $450. Also 6800GT AGP is "only" $355.
Also, on the lower end X300/SE => but those cards just suck so no need to mention them.
