I listed a recertified hdd just to have one there because the hdd prices are so high right now that you can either go with that choice or wait for the prices to come back down. I also listed the new 2011 socket CPU and MB so it would somewhat future proof and will do you for the next 2 to 3 years. Total for this build is $2074.93 and of course the components listed are for you to look through and decide if you want to go that way or go with the 1155 socket that would bring the price down considerably.
you may go to the wrong way i think
in 2008 i got an i7 920 and 2 gtx260s and plays very well till 2010, 3 years right? than i just overclocked the cpu and buy an HD 5870 and it works very well for now.
if you want a rig that fulfills your gaming demand in the next 3 years, i think 2k dollars is a bit too much.
if i were you i will buy an i7 2600K with a high-end gigabyte or MSI motherboard, cause the sandy bridge has the highest single thread performance for now and most games can not fully take advantage of more than 3 cpu cores. it means most games dont need a very advanced multi-core cpu that has 6 or 8 or more cores, they need one or two extremely high performance core(s) that dominate all other cores. so 2600K will be the best choice, because i didn't see 3930 get any significant gaming performance gain over it. i perfer buying next generation ivy bridge instead.
i will buy one HD 6970 or GTX 580 cause they are the best single core graphic cards currently. i only expect to upgrade the graphic card in the next 2 years if i suddently want much more gaming performance, like playing doom4 or quake5 or crysis 3 or something like this and the next generation graphics come out.
current games do not benifit much from an ssd i think, the loading time does not changes much if i remembered correctly. so i will just buy an 128GB ssd for os, and one or two large HDD for storage.
i think the totally cost maybe 1k or 1.5k since you've already have many other compments.
hope it helps
@kiss4luna i was also thinking the sandy bridge i7 2600 was hte way to go cause no pc game in a long time will use the relaly high end boards like the x79 so am swingin to a 1155 board and prosser with a gtx 580
