All awesome, thank you to all that helped.
I did the upgrade to the GeForce 7800 Go GTX a little over 2 weeks ago without a hickup, followed all instructions, and happy to report another success story
I been playing Serious Sam 2 and Splinter Cell Chaos Theory at 1920-1200 all settings maxed out... just breath^%$#%taking!
The graphics just pop out on the TrueLife, I find myself just taking my time in all levels just admiring the surroundings, truly cool stuff gang
First thing I did after the upgrade (besides latest bios flash etc) was to remove all the crap Dell installed in my lappy and I mean everything, I deleted the partitions got rid of Windows Media Center, just made a 10GB partition for Windows XP Pro and left the rest on second partition for games and other stuff. This ofcourse was a personal preference.
My 9300 came with the basic included ATI card and 512RAM in 2 256 sticks,I got that put away should I ever need to revert to original hardware for warranty services,hopefully never!
I got the 2 gigs of Kingston ram from NewEgg and the Linksys SRX400 from BestBuy (to match my LINKSYS WRT54GX4 router with SRX400, this router rocks gang specially paired with matching card) Only upgrade I got left is a better hard drive, I got the basic 60gigs 5400 rpm one included with the basic 9300, I got my eyes on the HITACHI Travelstar 7K100 80GB 7200 RPM 8MB Cache ATA-6, NewEgg has it for $155.
I havent had any problems at all with my rig, it is very stable and not a single crash in this 2 games I been playing. It does get a bit warm during intense gaming sessions but not hot enough that it can't be in your lap, but for this I am also thinking or getting one of those notebook coolers with the fans, if any one here has a nice one that fits the 9300 please let me know how mutch ans where you bought it, it would be a cool addition in more ways than one.
Thanks again gang!!! this thread was the last push I needed to buy my first lappy, no regrets but all the opposite... Arrooooooooooo!!!!!!!!
