I'll let you shop for bundles/deals/used/new/refurb/etc. What I'd build right now using my 8 years of building high-end workstations, 7 years in the IT field, and lifetime of being a PC gamer as the guiding experience: (Just so you know I'm not some schmoe giving you newegg's latest combo)
- Intel Core i7-3770K
- SilverStone Temjin Series Case
- SeaSonic X Series X-850 PSU
- GIGABYTE GA-Z68X-UD3H-B3 Motherboard
- Mushkin Enhanced Blackline 8GB PC3 12800
- XFX Radeon HD 7950
- Monoprice 27" IPS LED CrystalPro Monitor
I believe this to represent a great bang for buck that you won't have to upgrade for years, however, upgrade options will be available, because its a current platform. The case, PSU, and monitor will last you through several future builds. I have chosen brands that I have grown to love working with through the years based on service life and how they handle RMAs when something does go wrong. I have used each part listed in a build at some point or another aside from the 3770K as most users opt down for the i5 (against my recommendation). All of these items can be found at various places at differing prices.
For storage, really, it has to fit you. I do recommend a Samsung SSD that you can fit in, and at least a 7200RPM 1TB hard drive.
Lastly, if you're going to overclock at all, I can recommend coolers as well. I used to be a product tester for Cooler Master and Xigmatek and was able to use and test many coolers at certain points. Back in the day, I had a shortlived record for the 4th fastest air cooled Core i7 920 in the world.
Good luck, and happy building!

One more thing!!!! lol
I made a lot of assumptions on the computer usage habits would be, based on you placing this on a forum dedicated to gaming. You could lower several of the options on the build if you don't game very often. I still like having the extra head room. It prevents you from having to upgrade/open the computer again for a good while longer, as opposed to stair stepping upgrades. The HD7X00 series has a lot of great HT options as well via the HDMI out, if thats important to you.
Also, if you're primary listening method will be headphones, I recommend a decent DAC as well. It makes a huge difference in music/game sound quality.
