Maximum PC

I just bought me a new video card (EVGA 3MB GTX 580) to go with my new build.

So I have my old parts just laying stored away and I would like to sell them to buy me a new 1200w plus power supply for when I save enough money to buy another video card, I can run two 580GTX vid cards in SLI and have 6GB of DDR5 video card memory.

In my old set up I have two 7800 GTX OC Nvidia video cards (one shown in link below), an athlon 4000 chip, a XFi Falty one Platinum sound card, a Zalman 9900 Fan (not shown), 4 sticks of Corsair Ram with the scrolling marquee type to add up to 2 GB, and a Thermaltake 680W power supply. My mobo has issues, so other than parts, it is useless although it still works. It was an ASUS A8NSLI32 mobo.

I have a Dell 2400 video monitor now too that I would like to upgrade.

Here is hopefully a pic of my two old XFX 7800GTXOC video cards that I had before buying my new card. Any value to these?
