GFX - 6990 is a toad. For $725 you gonna get 762 fps in Guru3D's game test suite. Two 900 MHz 560 Ti's will give ya 100 more fps (862) for $460. A single 580 will do 616 fps for $480. The twin 560's top the 580 by 40% and the 6990 by 13% for less money

The ASUS P8Z68-V-PRO motherboard itself then, yeah we like it. It's that typical ASUS design that again is striking and offering a truckload of features. ASUS takes that Z68 chipset and then adds, adds, and adds. The end result is a motherboard with massive overclockability, great baseline performance and the industry's best EFI BIOS implementation. Seriously, the ASUS EFI (GUI based) BIOS rocks hard man, it's a great GUI and easy to navigate in environment. This motherboard is based of the new 14-phase Digi+ VRM to power the CPU plus anther two for the memory. The board is loaded with features including two additional SATA 6G ports (Marvel), USB 3.0, BlueTooth, the card features four DIMM sockets, two PCI Express x1 slots, two legacy PCI slots, as well as three PCI Express x16 slots, but don't expect surprises for multi-GPU support, since the Z68 chipset is identical to the P67 in this respect - just a pair of discrete graphics cards are supported in the x8/x8 configuration.
Cooler:
Budget Option ($30) - Hyper 212+
Midrange Option ($50) - Scythe Mugen 3
Enthusiast Option ($80) - Themaltake Silver Arrow
Liquid cooling has kinda lost its reason for being......the better air coolers are way more than what is needed for Sandy Bridge.

It's almost ironic that [air] coolers like this are becoming available just as processors transition to designs that may ultimately render them unnecessary; even overclocked to 5GHz, an Intel Sandy Bridge 2600K doesn't need anywhere near this level of cooling.
