PCI-E 2.0

Yea I just thought about that.
I think the 9800 and 3870x2's might be the last to take run on pci-e 1.1, but then again cant overclocking the PCI-E from 100 to 175Mhz increase the bandwidth? I'm hoping to keep my mobo untill 2009 and only upgrade cpu, gpu and maybe ram.

Bandwidth is a bit of a marketing thing really. AGP is actually still current in bandwith terms and I think its only beeten out in things like peaks for the synthetics. Don't think you would notice it in actual performance. PCI-E just offers more functionality, Dual GFX, Expansion slot unification etc. The best advance in PCI-E from AGP and PCI-E 1/1.1 to PCI-2 is probably the extra power It feeds the card. Its always best to buy the most recent kit though, so long as there isn't a silly premium on it... DDR3 anyone?
How can you explain the big performance loss when 8800's and 38xx's are operating in 4X ?

I'm actually mostly refairing to AGPx8 to PCI-Ex16 sorry. the lower down the scale you go the difference is ofcourse going to be more noteable. for instance if you where to compare a 939 AGP system with a x1950pro installed and a 939 PCI-E system with a x1950pro installed also you would see next to no difference... or even compare agaonst the x1950xt AGP or 7950gt AGP (true apples to apples comparisons) now I know these cards are not the very fastest but there are no very high end cards around at the moment to compare against but the 3850 and 3870 (but with GDDR3) will aparently be coming to AGP according to something gibbo posted a while back and I would be very suprised if you saw more than a 5-10% performance loss on the synthetic tests and Much less than that in Actual In Game Performance. Most of the bandwidth limitations are only for peaking spikes where very spacific tests will max out bandwidwith but your very unlikely to see 100% of one spacific graphical type in game at any one time. can you see where I'm going with that?

Because AGP 8x is faster than PCI-E 4x in 1 direction but not when Bi Directional.
There was a new faster AGP due but they wanted to sell you 2 GPU's so brought back SLI, which was old tech from the company they bought over years before.
Infact someone here claimed AGP could be made work with a SLI type set up (no clue on that myself)

the newer agp was that agp pro btw? i had that on my a7n8x but have never seen an agp pro gfx card.
and i think that agp could have suported an sli type interface as they did it over legacy pci and agp is mostly an extension of that but with grater bandwith as i understand it. the origonal sli worked in a different way than the voodoo implimentation i believe and other than the acronim its not really the same. hell voodoo gave us multi gpu gfx cards too. upto 4 gpus on one gfx card i believe well voodoo was the range 3dfx was the company sorry. but thats just a tad before my time really.

It was not the AGP Pro that was on all our recent Mobos like NF2 and even before (little sticker and plastic part to stop you putting wrong card in AGP slot), I had that on both AGP4x and AGP8x Mobos, think it may have been meant for Pro use Cards not Gamer Cards, but I know the Quadro did not use it.
And the peeps talking about SLI type set up on AGP, meant a new type of AGP also.
Asus and Gigabyte both gave us Multi GPU's on 1 card, the Asus was a 6800GT with an external PSU (good idea IMO), the Gigabyte was a 6600GT but downside was it only worked in the Gigabyte Mobo it was made for.

" AGP Pro
This was a rarely-used slot for cards that required more electrical power. It is a longer slot with additional pins for that purpose. AGP Pro cards were usually workstation-class cards used to accelerate professional computer-aided design applications employed in the fields of architecture, machining, engineering, simulations, and similar fields "
