lol wait until april, for the new nvidia, then later on might as well wait until september, for newer cards and other stuff then might as well wait until january 2013 and so on so fort, waiting and waiting you will wait forever even for newer GPU you don't need to wait for them a hd 6850 and gtx560ti gtx480 can perform well in games right now and even if you do rendering they are enough unless you do workstation and other stuff,
the lga 2011, intel i7 3930K,msi x79a-gd65 8D, gtx 560ti 1gb/2gb or 6950/6970 amd's and some nice cooler and case, its enough to last you for a while before you need to do some serious overclocking or change some parts, imo,
my i7 3930K with 2011lga mobo, cost me the same as my i5 2500k, difference is i got a razer mamba/razer vespula/seagate hdd on my i5 2500k while on my i7 3930k i git no hdd no mouse/mpad but i got 32gb ram intead of 16gb
