HELP with my XPS 1730 Please!!

Good morning everyone..
I would need your help, thank you in advance!
I have a T7700 processor and 2 gb Ram 667 and dual 8700 SLi.

1)I'm buying on ebay the upgrade of dual 8800 gtx sli because in italy is not available. On ebay the power seller says that he is selling the 8800 gtx with core G92!! the same of 9800 GTX!! is that possible???? Anyway, is this worth the USD 1000 I'm going to pay?

2) I want to upgrade my RAM. As far as I know I can only get 2x2gb at speed of 667. Is that right? It's not possible to upgrade to 800mhz speed?

3)Do you guys think that processor T7700 is going to be a bottleneck for gaming soon? Will it be possible for me to upgrade to better processors?

Guys thank you very much for this great forum!!!!
cheers

Question 2 Goto

Question 3
That may be a little hard...

 

the 9800m gtx has 116 shaders cpu
the 8800m gtx has 96 shaders cpu

 

remember, you need SO-DiMM Memory for your laptop thats PC5200.

 

Thanks a lot guys for your precious help!
Just that my last question regarding the processor upgrade... I assume is not possible at all, right?

Thanks!

 

All Dell's now should be CPU interchangeable.
Laptop's are now fairly mainstream in CPU, MEMORY and HARD DRIVE upgrade ability.
Simply look at what is available for sale in your brand laptop in the CPU category. This is a bonafide for sure you can upgrade someday when prices drop to that most expensive CPU choice.

And the changing out is straightforward. Just look at your laptop's owner's manual .pdf. Or ask on this great forum.
