Intel Pro Wireless vs Dell cards

I'm trying to figure out which wireless card to get in my XPS Gen 2

Right now I have it configured as the Intel Pro 2915 Internal Wireless a/b/g but that's $20 more than the Intel Pro Wireless 2200 b/g and $25 more than the dell internal wireless 1370 b/g.


Is thie "2915 a/b/g" that much better than the other 2 cards? If it helps at all, my system specs are:

Inspiron XPS Gen 2;Intel® Pentium® M Processor 760 (2 GHz/2MB Cache/533MHz FSB)
Operating System: Microsoft® Windows® XP Home Edition
LCD Panel: 17 inch UltraSharpTM Wide Screen UXGA Display with TrueLifeTM
Memory: 1GB Dual Channel DDR2 SDRAM at 533MHz 2 Dimm
Hard Drive: 60GB Hard Drive
Video Card: 256MB NVIDIA® GeForceTM Go 6800 Ultra
Primary Battery: 9-cell Lithium Ion Primary Battery (80 WHr)
Network Card: Integrated 1 Gigabit Network Card and Modem
CD ROM/DVD ROM: 8x CD/DVD burner (DVD+/-RW) with double-layer write capability


Wireless Personal Networking Card: Intel® PRO/Wireless 2915 Internal Wireless (802.11 a/b/g, 54Mbps)

 

I just bought a i9300 (very similar to XPS gen2. I decided on the Intel 2915 for a few reasons. First is Intel is a known name and make these cards for MANY laptops. Second, I had not heard much about the Dell version. Third, with the Intel version you activate the Centrino technology, since your processor is Intel they will work better together.

Now I have no experience with Dell Wireless NIC cards. I have worked with most brands at work: Cisco, broadcom, Linksys

Dell Ispiron 9300
Pentium M 1.8
1024MB DDR2
Go6800 256MB

 

I actually considered going with the i9300 but I couldn't pass up the 30-40% more powerful video card on the XPS 2 (especially as a gamer).
