Stingray98,
$750 isn't too bad to pay if it's working fine. I'd have to sit down and crunch some numbers, and know a bit more detail. However, if you factor in Tax and Shipping, and Windows it's likely closer to $500 you pay for the hardware.
If the screen is okay and worth at least $200 then it's $300 for the System. The CPU is about $200 which leaves $100 for everything else so it's pretty good, again if working fine.
The DDR3 memory alone is pretty expensive for 32GB.
GTX560:
This card isn't the best card now, but I did play SKYRIM nicely on my HD5870 1GB card. I did find that the official HD texture pack killed performance enough that I removed it, but with a few tweaks I could stay mostly at 60FPS. I just hate a game that gets sluggish (VSYNC ON below 60FPS resynchs to 30FPS. VSYNC OFF gets screen tearing.)
I hope this helps.
*The more I look at the specs for this machine, the more I think the following:
"That's an awesome deal, or you're getting screwed somehow.."
