Help choosing processor for HP notebook

I plan to buy a new notebook within a couple of months, either a PC or a MacBook Pro (that's another story---I've used PC's for almost 20 years but am looking into the Macs). My question concerns processors.

I've "built" two identical HP 6000's at www.shopping.hp.com:

Vista Home Premium
15.4" WXGA BrightView Widescreen (1280x800)
256MB NVIDIA(R) GeForce(R) Go 7400
HP Imprint Finish + Microphone + Webcam
2048MB DDR2 System Memory (2 Dimm)
160GB 5400RPM SATA Hard Drive
LightScribe Super Multi 8X DVD+/-RW w/Double Layer
Intel(R) PRO/Wireless 3945ABG Network w/Bluetooth
6 Cell Lithium Ion Battery.

The only difference is the processors:

1. AMD Turion 64 X2 Dual-Core TL-60(2.0GHz/1MB) OR

2. Intel Core 2 Duo T7200 (2.0GHz/4MB L2 Cache).

What kind of difference would I notice between the two processors? The AMD computer would be $90 cheaper, but the processor has only 1MB of cache while the Intel has 4MB. How much does that affect speed?

Or, could I save even more by stepping down to a slower processor? For instance, the AMD Dual-Core TL-56(1.8GHz/1MB) would be $75 less than the AMD Dual-Core TL-60 (2.0GHz/1MB). The Intel Core 2 Duo T5600(1.83GHz/2MB L2 Cache) would be $100 less than the Intel Core 2 Duo T7200 (2.0GHz/4MB L2 Cache).

I thought I had read somewhere that the AMD with its Turion Dual Core chips had fallen behind Intel with its Core 2 Duo chips. Because I tend to keep my notebooks for several years (my present HP is four years old), I want the get the fastest processor practicable.

Thanks.

 

i'd go with the intel... im not completely sure but if money isnt an issue between the two...

4 is better than 1 lol
