PCI Express

Hello, I was planning on buying a Graphic card such as a GeForce 9800GTX with PCI Express 2.0 x16.

The Currently Motherboard i have is a PCi Express x16. Would the card work on my motherboard?

I was planning on buying a 3 Way SLI motherboard after this so the card would run faster on a 2.0 PCI express slot.

Its possible to use this card on my current motherboard right?

So are you guys sure?

I have a Dell Dimension 4700's motherboard, I currently use a GeForce 8500gt so its a PCI Express x16 right?

I can buy a PCI Express 2.0 x16 and it wont be a problem?

Well, i was planning to buy a new Power Supply. Currently i have a 350W PSU.

The Whole computer Consumes around 200W along with the Fans on the Antec Nine Hundred.

I was going to buy the Antec 850W Quattro. It was on sale today with free shipping for around $124 on Newegg. It was 200+ before and im not sure if the price would go up after black friday.

I was planning it for the future. to buy a new 9800GTX every 2-3 months for SLI after the first one.

I've found out i only have 3 Molex for the Graphic cards 6 pins. It needs 4 molexes. Is it possible to use it with 3? Or does 4 really necessary?

Should i just Buy the 850W since its on sale for only today? Then buy a 9800GTX some other time?

I would suggest to sli more powerful cards and not weaker cards in tri sli. http://www.tweaktown.com/articles/ [...] index.html The old but powerful gtx260 are hard to turn down thanks to the price cuts .

No dell dont have sli but he's planning on get a 3 way sli mobo. The most important reason those cards venom just mentioned needs pci e 2.0 is for the increased power that pci express 2.0 slot provides compared to pci e 1.X

Haha, thanks a lot guys.
I decided to buy the "Corsair 750TX 750W SLI Ready CrossFire Ready" PSU today. It costed around $112

I've read really good reviews on the psu and it was affordable so i bought it :]

Next to buy is the GeForce 9800GTX then a LGA 775 NVIDIA nForce 780i SLI ATX Intel Motherboard and 2 more GTX's Afterwords.

There is 1 Final question i'd like to ask.

This Motherboard "Nvidia 780i 3 way SLI"

http://www.newegg.com/Product/Prod [...] 6813188024

says that it works for everything core 2 duo,quad,extreme, and then Pentium.

If i switch my motherboard after i buy the graphic card, would my LGA 775 3.2Ghz(2 logic cores) Pentium 4 work for this board?

Lol p4? Even the latest celeron kill those chips. How bout a cheap E7200 with some overclocking till atleast 3.6 or if you have extra a e8400 would be enough for a 9800gtx.

Heck if this guy knows how to raise the fsb any core 2 will do.
