Help me price my PC!

Hey, guys, I am looking to sell my current pre-made PC to upgrade to a beastly system that I'm looking to build. I'll likely be making another topic asking for some help with building the new one, too. What I need help with here is pricing out my current PC. It's an Alienware Andromeda R5. I'll list the specs out. I see one on ebay right now with a slightly better processor, but a much worse graphics card (I upgraded the one in mine) for $800 with a watcher. Mine is also in better cosmetic condition and even has the original box, so I reckon $800 is a good jumping off point, at least. Here are the specs!

Evga GTX 660 ti

1 tb HDD 7200 RPM

Intel i5-2320 @ 3.00 ghz

8gb RAM

Blu ray combo drive

Any idears?

I already posted in your other topic. Don't make multiple topics; merge them.

If you still want assistance with this all, send me a PM with the specific parts you have (+ links to product pages).
