Ok I have decided on this monitor
Asus SonicMaster MX299Q 29" Ultra Widescreen Ultra Slim Bezel LED Monitor
Which graphics card for this monitor please
Depending on your budget and if your motherboard support crossfire at x8/x8 (if you are unsure, try to finding out the exact model of your MSI Z68A (e.g. G43, GD55, GD65, GD80 etc):
1) Best bang for bucks option
Most bang for bucks would be a pair of 7950 at £190 each (£380), and each card comes with 1 AMD Radeon GOLD Reward Ticket, which you can claim 3 free games of choice from the game bundle list (so 2 tickets you can claim 6 games):

But as I said, need to check what motherboard you got first.
2) Fastest single card option
If you motherboard don't support crossfire at x8/x8, then you might consider the 7990 pre-order at £479.99. This will be the most powerful single card option, but not as good value as getting a pair of 7950, and I'm also not sure about the details regarding the free games or ticket with this card:

3) Fastest single GPU option
If you are not confident on the reliability and performance scaling of multi-GPU, you could considering the GTX780. It is not exactly good value for money, as it is slower than the cheaper 7990 if crossfire performance scaling in games is not an issue, however in games that has poor support for multi-GPU, the GTX780 could be faster:

However, do bear in mind that AMD's gonna launch their next gen card next month, the chances are their flagship card will target the GTX780, and most people are speculate that it wouldeither a) offer better performance than the GTX780 and/or b) only equal to the GTX780 but at a lower price.
