Need helping deciding on which system to upgrade to

I am in the process of searching for a new system to upgrade to from my now 5 year old computer. I don't have time to build it myself in between work and school so I am going to be purchasing one complete with a warranty. Please do not suggest a DIY buy the parts from newegg.com solution I have neither the time nor the inclination at this point.

The system will primarily be used for gaming and needs to be able to last another 4-5 years.

Preferences:

Price between $2,000-$2500
Intel Processor
Min. 6gb of RAM at a min. of 1333 Mhz. DDR3
X58 Chipset MOBO
Prefer 2GB GDDR5 ATI Radeon™ HD 5970 or equivalent GPU min.
1 TB SATA II hard drive min.
i7 920 min.
3 yr warranty min.

Do not need monitor, mouse, speakers, or keyboard.

The systems I am considering right now. If anyone has any thoughts about which to select I am looking forward to them.

Hi newcomer and welcome to the Tom's hardware forum.

IMO are expensive, try to build the rig yourslfe from newegg.com and compare the price. Maybe you can get the same performance with less price.

Thank you for the information on the prices for the individual parts but as I said I have neither the time nor the inclination to build this myself right now. I'm more looking for any ideas on which of the systems I presented would be the best value for my money.
