$2k is still low budget for a cracking rig.
For best performance for the buck you still have to consider buying 290x. You may be able to snap some decent bargains on ebay but you still have to calculate around 250-300$ for one gpu.
The biggest problem for your budget is probably the fact that costs go up exponentially the more gpus you put on one board (second powersupply, case, cooling).
For $2k if you are lucky you can go for 4x290x that leaves you with around $800 for board, cpu, ram, case and powersupply. A 1500W powersupply is costly but neccessary and shouldn't be cheaped out on. There are some discussion on which boards to use, choose one on which you can put all gpus without the use of extender since you may need another $100 just for the extender and another 100-200$ for the casing to arrange the gpus. Also watch out which CPU you choose since there may be a difference in the pcie lanes they can address, i7 >4770k is a good choice.
