Motherboard Question

[Walrus]

I am building a PC and my graphics card is a Gtx 670 FTW 2gb and has a 3.0 x 16 PCI slot, while my motherboard only has a 2.0 x 16 PCI slot (GIGABYTE GA-Z68XP-UD3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard)
Should I buy a different motherboard that supports 3.0 for future proofing my machine, and will it make my graphics card run slower if I use a 2.0.
My Current Build:
Intel i5 2500k
Gtx 670 FTW 2gb
Sandisk Extreme 120gb SSD
WD Caviar Black 500gb
Corsair tx650w
Samsung 22x Dvd Burner
8gb Corsair Vengence (2x4gb)
Cooler Master 212 Evo
Storm scout case
Windows 7 Home
GIGABYTE GA-Z68XP-UD3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard ( Please feel free to suggest other motherboards)

Thanks,
Walrus

Nope waste of money PCI-E 2.0 has plenty of bandwidth for any card in the foreseeable future.

The new PCI-Express 3.0 interface can provide around 1% performance boost for both HD 7970 and GTX 680. While this confirms that both cards provide working support for Gen 3, such a small improvement is clearly not worth worrying about. It certainly does not warrant buying a new processor or motherboard. PCI-Express is forward and backward compatible, so any PCI-Express graphics card will work in any motherboard's PCI-Express slot, no matter which version each component supports.

Thank you very much for the link and information.
Should i upgrade my chipset for better performance such as going to the z77?

It won't add more performance, but it wil ladd other features. W1zz's testing shows about 1% differnece form PCIe 2.0 to PCIe 3.0, so there is very little to be gained there with a single card.

In your opinion what motherboard would be the best for me. Budget of $180

get the 2.0, by the time GPUs will really NEED 3.0, you wont need that mobo anymore
