I have a Vizio 3D TV that I have been running off an old i7-920 Gateway that I put a 560Ti in. Want to upgrade and have a nice case that doesn't look ridiculous next to my other A/V equipment. Any suggestions? This is what I'm thinking so far. The PSU might seem like a bit much, but I want to throw in another 670 at some point. Also, the amount of RAM may seem ridiculous but I am a champ at keeping dozens of things open at once and currently I easily run with 75% of my 8 gigs chewed through the majority of the time.
I agree with Deemo13 in that your current system should be more than sufficient, but if you really want to upgrade, you could probably sell your current for a few hundred to defer the cost of your new system.
