You can always go for a GTX280 who's price is coming down like anything.. will cost you around $250 in a while.. Also you can buy a 3GB DDR3 kit and upgrade later on when you have the cash. =)
Go for a cheaper screen. One around 10,000 to 11,000. You can save much there. I won't recommend a 690 here since it's a mid tower and the new graphics card and stuff are relatively longer than the old ones and thereby recommended you a full tower , so we cannot cut out on that. Maybe get a Thermaltake full tower for like 7500 or so. (Not so sure)
And if you buy next month , i'm quite sure you will save round bout 10,000 more. Trust me. X58's going to be slashed by 2000+ next month.
Price of the Quad's will drop drastically. i7's will also become a little more affordable but don't expect much on that.
Graphics card as always are expected to be cheaper over a period of time.
There is also a rumor that the GTX280 will be shut down due to release of GTX 260 Core216 , GTX285 and GTX295. But yeah that might not be true.. who knows what nVidia has on mind. So overall i recommend you buying your rig in 1st/2nd week of February you will eventually save a lot on the same rig.
Happy Purchasing. =)
