CPU:
Intel i7 3770K - $310 (You could drop it down to $210 with the i5 3550 which is a really nice chip as well, if you aren't considering doing anything really CPU intensive like video processing then you might as well)
Mobo:
Asus Maximus V Gene - $200 (There are tons that will work and for cheaper too... just look for the ports and features you want along with good reviews and price and you could go down to $130ish easily)
RAM:
8GB - $45 (As said in my other thread it's all basically the same price and doesn't matter much, guess you could go for 16gb but you really wouldn't need it so why spend extra)
GPU:
GTX 660 Ti - $300 (Card is brand new and at a great price for performance, plus you'll get the annoying exclusive PhysX feature with an Nvidia card.
HDD:
Intel 520 series 120GB SSD - $130
Western Digital Caviar Blue 1TB - $90
Total: $1075
You could add a bit extra with another 500GB or 1TB hard drive for backups, or save money by not investing in an SSD. With that budget I would recommend it as there is a significant performance increase in general use. As stated before, you could also cut down by going to the high end i5 instead as you really only get the benefit of an i7 if you're doing serious CPU work (just games won't really take advantage of it), and a cheaper motherboard depending on what you want is always an option. You *could* spend less on a GPU also, but again with that budget you might as well go for something real nice that will last a while. 16GB of RAM would only cost about $40 more, but it's very unlikely you'll need the extra memory for a long time, and by that time it will be crazy cheap like 8GB is now.
Good Mobo brands: ASUS (ASRock is just rebranded), Intel, GIGABYTE
