I'm very glad I finally decided to fork out the cash to upgrade my master computer. Before I had a quad core AMD with 16GB of ram which was really nice but shockingly I found that it wasn't quite enough power! I do a TON of web work and such so I usually have at least 200 internet tabs open between Waterfox, Google Chrome, Opera, and occasionally Internet Explorer. Add to that Photoshop, a DVD burning program, and a splattering of other programs and the computer just wasn't powerful enough to be my main rig anymore. And on top of that I'm getting more into gaming. But anyway, this is what my master machine has now after the upgrades:
*3.5Ghz (3.9Ghz Turbo) Intel Core i7 3770k Quad Core Processor (4 Cores & 4 Threads)
*32GB DDR3 1600Mhz Corsair Dominator RAM (4 x 8GB)
*120GB Solid State Drive (OS Drive)
*4TB (4 x 1TB Hard Drives) Storage
*Dual Layer Samsung DVD Burner
*Antec True-Power 1200 Watt Modular Gaming PSU
*Windows 7 Ultimate x64
The graphics card isn't really worth mentioning. It was just some $60 thing from Microcenter to get me going. I'll replace it eventually, but for now...... Anyway, well this machine is now worth around $2,500 - $3,000 depending on how well Craigslist is doing. I was going to hold off on upgrading, but a guy that was really hard up for cash sold me a complete gaming rig with the motherboard, processor and SSD I have now so I put those into my main rig along with 32GB of RAM I just got from Microcenter for $210. I put my older motherboard and other parts into the case of the computer he sold me and now I've got two new computers! The best part was he sold me the whole other computer for just $500. LOL. I should be able to tear through just about anything with this machine.

Here's an old picture I took of it (I have the same case as in this picture I took before):
