What exactly does PCIE-2.0 do compared to PCI-E?

Would I have to upgrade my motherboard to one that supports PCIE-2.0 in order to upgrade my graphics card to an EVGA 9800gtx+ (PCIE-2.0 Graphics Card)?






And slso, I'm unsure if my 550Watt Zumax Power supply will support a 9800gtx+

Actually, That is the exact same power supply I have :D





If you think the 9800gtx+ would be a bad decision, what would you recommend I buy?
My price range is 150-300$ to upgrade my AMD 4200+ and EVGA 8600gt (SLI)
 
This card would blow that one away:

Sapphire 4870 1GB Toxic edition. Probably pull less power as well.

I see the 9800GTX+ has come down in price a bit, so it's really not as bad a choice as I thought for the price. A comparable video card is the 4850:

A GTX 260 can be a great buy as well. About the same performance as the 4870 I linked or perhaps even better, and looks to be less these days:

You can run any single PCI-E card, but you cannot crossfire. The chipset only determines crossfire or SLI, in respect to GPU.

You can SLI, but really you would be somewhat limited by the CPU. I think either of those cards you have chosen are pretty nice for the price. The GTX 260 I linked is a faster, newer version than the one you have linked. 216 processors as opposed to 192, and it does make quite a difference.

Still I think it's kind of cool that all the cards we've listed pretty much reflect a good cost/performance ratio. It's been a few weeks since I looked closely. Choose what you can afford and you should be happy with the results.
