ok Folks building m first computer. My mobo had 3 pci slots.

EVGA 132-CK-NF79-A1 LGA 775 NVIDIA nForce 790i Ultra SLI DDR3 ATX Intel Motherboard - Retail

gms cool brought to my attention that the 9800 gtx's are at a smoking price. Tommorow I need to change my order so my question is.

2 x 9800gtxs and a physiX card?

Same as above sans physix card?

3 x 9800 gtx's?

3 x 9800 gx2's (is that possible or does each card take up 2 slots?)

and last but not least...

Whata bout 1,2,or 3  ge force 280's???

PhysiX cards aren't worthwhile to put money into them, there aren't any end products which utilize it...So, get either two or three 9800GTX's or two 9800GX2's, if you're insane enough to spend that much money on that many...Note that only two 9800GX2's can be put in SLi, there aren't any drivers which would allow you the use of three 9800GX2's...On top of the hardware and space limitations, you just simply can't fit three 9800GX2's on a  ATX motherboard...

Three-Way SLi is (So far) available only to these NVIDIA GPUs:

GeForce GTX 280

Geforce GTX 260

9800GTX

8800ULTRA

8800GTX

And these NVIDIA motherboard chipsets:

nForce 790i Ultra for Intel

nForce 790i for Intel

nForce 780i for Intel

nForce 780a for AMD

nForce 680i for Intel

If you have that much money (AKA more money then sense ) however, you'd be better off waiting to buy the GeForce 280's and 290's...Or getting three 260's in Three-Way SLi...But GeForce 280's and 260's are overpriced and are underpowered when if you check its performance to price ratio...So they aren't really worthwhile until they have a significant price drop...

The best deal right now, for the money, is getting two or three 9800GTX's...Simple as that...

IS the performance of the ATi HD 4850 and 4870 hindered by using a PCIe 1.1 slot? Mainly asking about the 4870 because of the GDDR5's bandwith.

according to the reviews I've read, it makes very little(if any) difference. 

The GDDR 5 is on the same board with the graphics core, so the bandwidth to the GDDR5 goes across the board, not through the PCI-E slot.   

Also, nVidia has recently released drivers that allow you to do PhysX acceleration using your graphics cards(GeForce 8xxx series or above), rather than a PhysX card.  So, there really is no need to get a PhysX card.  nVidia recently bought Ageia, so they may not even offer separate PhysX cards for sale much longer.

will i be able to run my 2600XT its kinda c**p but yea so can i run it.

 unforunalty its diactivated  http://www.newegg.com/Product/Product.aspx?Item=N82E16814241064 which is disapointing...

I did some research and i found out that my motherboard is PCIe 1.1a. Does PCIe 1.1a work with 8800gt? Whats the difference between PCIe 1.1 and 1.1a? I tried googling it but i cant find a clear answer

i have asus m2a-vm and it has 690G chipset

ECS NF650iSLIT-A

A review.  http://www.legitreviews.com/article/466/1/

And that link in previous post has the specs

In single slot mode, the slots are PCIE 1.1 x16.

In SLI mode the PCIE 1.1 slots operate in shares x8/x8 mode.

Does anyone know about 8800GT + PCIe 1.1a?

...

Do people really not read the posts in this thread?  How about the title?!

YES THEY ARE COMPATIBLE, YOU LOSE ABOUT 2% SPEED BUT IT WORKS JUST FINE.

The Asus p5Q PRO has serious issues as was pointed out here.  http://www.eggxpert.com/forums/permalink/397633/396967/ShowThread.aspx#396967

Viewing  results googling, it certainly appears so.

In regards to what?

All newer current generation mobos and video cards are all PCIE 2.0 x16 now. 

Hi i know i asked this someplace else but i just want to verify,Will 1.0 PCI-e Sound Cards definitely work in 2.0 PCI-e slots? for example this;

http://www.newegg.com/Product/Product.aspx?Item=N82E16829102019

hmm is that 1.0 or 1.1 PCI-e  im still new to the PCI-e world lol.

thank you in advance for help.

.... Except for some Asus motherboards and video cards (listed in thread), the TITLE of theis thread still goes.

PCIE 1.1 and 2.0 are cross compatible with some performance diffrences. Sound card should work.

Yahoo! There go my worries about getting the HD3850 I was looking at, as long as the performance isn't affected its a go.

Performance will be the same.

Even the best cards on the market can still not use the full bandwidth of 16x. 

 Would this affect my performance? I have a 680i lt motherboard but i have pci 1.0 slots only. I was wondering if getting 2 gtx 280's will do no good to me. Will this bottleneck me? I also have qx9650 cpu (not overclocked), 4 gigs of pc6400 ram  (but i use only 3gb), 2 500gb raid o , rosewill 950watt, windows vista sp 1 32 bit,

Now for the real toughie: Q6600 or Q9300?
