I agree with amraam. Ivy Bridge is the next step up from Sandy bridge. That is when you want to get PCI-E 3.0, when the full support of it is out on the market.
@ Fowler002: Just because I am an AMD user does not mean I know what I am on about. I chose AMD because of my budget at the time and because of the new Bulldozer chip. I have just designed my own case, my new system and the components I will be adding into it. So please do not patronise me just because I am an AMD user. I have had Intel systems in the past and loved them. I OC'd my old P4 from 3.2ghz to 4ghz on water cooling. I ain't stupid and don't like it when you say I don't know anything about intel, so please keep your opinions to yourself.
PCI-E 3.0: This is great technology and I will upgrade to it, when the time is right. Their is no support from ANY GPU on the market for the next year to year and a half for PCI-E 3.0. And to what Fowler002 was on about, Ivy Bridge will be out within a year (rumoured back end of 2012, as they don't want to get rid of Sandy Bridge just yet) and that will have PCI-E3.0 support. But you will have to wait until Nvidia and ATI decide to bring out their next generation of cards and their next cards may not even have PCI-E 3.0 support on them, that may have to wait until after the next gen cards are brought out and the newer cards after that will have the support. Dont spend money now, when Ivy Bridge comes out (ok they can be used in lga1155/SB boards) but not run at full speed, a new board will more or likely be required to get the most out of the new Ivy Bridge Processors. Which means, spending loads of money now on a new board, when he has one of the best Z68 boards out, and then if he updates to IB at the end of next year, he may have to get another board, which will have PCI-E 3.0 on it as standard.
@ AGD: Save your money atm, stick with the awesome board you already have and save up. ALl you need is a good GPU and your set dude!
