Not sure what to do

Got my M17x last week and keyboard took a crap first day... They sent a guy over who changed the mobo, it fixed it for 3 hours.... Later that day after powering it up the video cards took a crap..... After 3 hour on the phone they are going to replace it. System config is :
Intel® Core™2 Quad Q9000 2.0GHz (6MB Cache, 1066MHz FSB)
Dual NVIDIA® GeForce® GTX 260M, 2GB – SLI® Enabled
17-inch WideUXGA 1920x1200 (1200p)
4GB Dual Channel DDR3 at 1333MHz
250GB 7,200RPM w/ Free Fall Protection


Before they replace it I was wondering if going to the i7 & ATI is going to be worth the extra 400ish $$$? Config is below:

I am wondering how much better the performance will be with this:
Intel® Core™ i7 820QM 1.73GHz (3.06GHz Turbo Mode, 8MB Cache)
Dual 1GB ATI Radeon™ Mobility HD 4870 in CrossfireX™
17-inch WideUXGA 1920x1200 (1200p)
4GB Dual Channel DDR3 at 1333MHz
250GB 7,200RPM w/ Free Fall Protection


Any thoughts or suggestions would be greatly appreciated. Only thing I didnt mention is that I would have to wait about a month for the R2. Is it going to be that much of a difference in performance? Only thing i use it for is gaming & spreadsheets

 

yeah way worth it. more upgrade paths for new version. $400 more but much better hardware.

 

whats worth more the 200mhz for the 820 vrs the 720 or a RGB LED screen cuz id definatly go that route

 

You probably won't regret it

 

lemon law. is there one for computers =) id get the newer model for the extra dough if you can swing it

 

if you complain enough about legitamite problems im sure they will give in eventually

 

Wow two problems on the same day! that's very unlucky.
Like it was said before you won't regret it.

 

Thank you for all the input! Turns out that the new system is going to cost 629 more.... Guess I was really getting an amazing deal. I knew that I hit the wall because the rep I spoke with told me he had to transfer me to the EPP site because the price I had was too low and he couldnt match it. After another hour dealing with them, I needed to head out and scheduled a call back. Of course no one ever called me back...

 

The only draw back is the Waiting.

 

Well forget DELL, I am going to give my money to a different company. Those jokers lied to me telling me that my system was going to be shipped 4 different times and it still has not shipped. I ripped the customer service manager a new hole and told them when they wind up sending me the system it will be refused.
