need advise on CPU T7250 vs T7500 + is it worth waiting for new offer?

I am about to buy XPS1530 with the following configuration:


Intel® Core™ 2 Duo processor T7250 (2.00 GHz, 800 MHz FSB, 2 MB L2-cache)
15.4" UltraSharp™ Widescreen WSXGA+ (1680x1050) TFT Display with TrueLife™ (still not sure, maybe I'll take lower resolution)
4096MB 667MHz Dual Channel DDR2 SDRAM [2x2048]
250GB (5400RPM) SATA Hard Drive
NVIDIA® GeForce™ Go 8600M GT with 256MB dedicated graphic memory

1)

the offer for this XPS expires on 13th of Fabruary, do you think I should wait for new offer and expect it could be cheaper? I don't know what's it like usually with Dell, should I expect price decrease or increase? Or is it probable that there will be more options available to choose from regarding HDD and LCD

2)
I was trying to get faster HDD with 7200 RPM but it seems impossible therefore I would like to know your opinion if it is worth to spend +100€ on getting CPU T7500 with 4 MB cache.
I wonder if I feel the difference if my HDD will be relatively slow. I am waiting your comments.

Thanks for your comments guys!!

 

7200 is the fastest you'll get in a Dell notebook, or ANY notebook as far as I know.

 

The fastest I could get with this configuration is the one below:
Intel® Core™ 2 Duo processor T7700 (2.40 GHz, 800 MHz FSB, 4 MB L2-cache
but its too expensive,

so what do you reckon as for my questions?

 

i think you should wait till the penryn is out on xps 1530....i think they make a hell worth of difference....however expect the prices to soar a little on the introduction of penryn

 

for the second question.....the max speed of ur computer on most occasions is equal to the speed of the slowest component....ie the hard disk......so i think u should go with the 72k rpm and 160Gb option and use an external drive to store huge files if u have any.......u can buy the drive from savings on the T7500 i think

 

Hi kuncheesh,
thanks for your opinion,
as for waiting on penryn I don't know if I could hold as I have been without a computer for good few months especially that there is no clear indication when penryn would be introduced for XPS model

when it comes to HDD I don't have option of choosing 160 GB 7200 as there are only two options available, (in fact only one reasonable)

250GB (5400RPM) SATA Hard Drive [Included in Price]
64GB Solid State Drive [add € 1,230.01 ]

I asked a rep on dell chat only to find out 160 GB 7200 is not applicable to XPS

so with having just one option for HDD do you think I should stick to T7250??

 

if u need a machine fast and it only comes with the 54k hdd then go ahead.......t7250 is fine.......it will do all stuff with decency.........i have been using this for a few months from now and hasnt seen any troubles

 

Don't spend the extra money on the ram upgrade. Get the 1GB option and buy two 2GB sticks from newegg, you should save upwards of $100.

 

Hmm I disagree the difference will be marginal unless media encoding. The increased battery life will also be no big jump.
