Graphics Card Upgrade... Will it work with my system?

[QuantumX]

Gentlemen,

I currently have the following:

Gigabyte GA-EX58-UD5 Intel X58 (Socket 1366) DDR3 Motherboard
Intel Core i7 920 D0 Stepping (SLBEJ) 2.66GHz (Nehalem) (Socket LGA1366)
VTX3D ATI Radeon HD5870 1GB DDR5 Dual DVI HDMI DisplayPort

I was looking at a complete upgrade for CPU, motherboard and GFX card, but a lot of people are saying there is little be be gained upgrading the CPU..

So the question is can i just go to the latest GFX card? I'm looking at buying the

MSI HD 7970 OC 3072MB GDDR5 PCI-Express Graphics Card*

But i'm unsure if the motherboard will support it? i thin my card in PCIe 2.1 x16, and the new one is PCIe 3.0 x 16? and TBH i'm unsure what this means...

PCI-e 3 is backwards compatible so 7970 will work in that motherboard. As for upgrading the CPU and motherboard I wouldn't right now, wait a few months and see what Intel comes out with then.

Will there be a performance hit?

Are there any disadvantages or issues?

That I7 is a quality chip still and get a decent overclock on it for modern games. 4Ghz should be good for frame boosting performance.

Using a PCI-e 3 card in a PCI-e 2 slot will have no performance hit as the 7970 will not even use the full bandwidth available in the PCI-e 2 slot anyway. So no performance hit.

A GTX 690 goes like a bat out of hell on X58.
