Hi, I've noticed that the PCI Express interface seems to be very similar to the PCI 2.x interface. Is the PCI E backwards compatible with old and new extension cards? Also, I have seen AGP Express. Is this a different slot altogether from the PCI Express interface? If so, is this interface compatible with the current AGP 8x graphics cards? thanks

PCI Express is not backwards compatible with current or older PCI expansion cards.

AGP Express is similar to AGP but completely different from PCI Express.

Some AGP cards will work with AGP Express - not sure on specific models.

if your gonna get a new graphics card get a agp

PCI may be the new kid on the block and it may be 4x faster then AGP 8x , but currently nothing on the market is going to harness its potential - get AGP now becasue at this time PCI-E is to expensive

not to mention the motherboard prices :D

Care to provide your logic behind that statement? Granted if the budget is tight then get AGP as PCIe has no benefits, but if you have money to burn or what a system thats futureproof then PCIe or PEG does have its merits.

Define: futureproof

Whatever you buy at the top range today will at the lower end in two years. How far can you futureproof your setup?

If you go out tomorrow and decide to buy an entirely new system and you go with old technology such as DDR, AGP and Socket 478, now in 6 months time when you decide you'd like a lil more RAM or a faster video card its going to be harder to source, and most likely more expensive as its old technology. The future is PCIe, so let say in a years time you decide that you want to upgrade the above system, at this point everything will need to be upgraded as DDR, AGP and Socket 478 are no longer avaliable. Now had you brought PCIe back when you originally brought your system you could reuse your old video card, it might not be the fastest but atleast you can get into windows etc. This would allow you to invest more money in a quality motherboard, CPU or RAM, or perhaps at the time the video card market is very unsettled like is at the moment with new technology demanding a premium. Reusing your old video card would allow you to sit back and wait for a bargin.

Futureproofing might not mean that your always have the best preforming peice of hardware, but it gives you options allowing you to spend your money more wisely.

Another example, i have a couple of friends who've just upgraded to X800XT's and Socket 939 Athlons. There now kicking themselves with VIA release of the K8T890 and the impending release of the nForce4. They want to upgrade to motherboards with PCIe in the future, fortunatly their CPUs and memory will still be compatiable, but they will struggle to find the money to buy a PEG graphics card as good as there current AGP card.
