dell 9300 configurations for 4-tabling
 

i am about to purchase the dell 9300 and would like some opinions on upgrades. i would solely be using this computer for 4 tabling with poker tracker and GT+ open. i would of course be upgrading to the wuxga screen for this but am clueless about other upgrades. i would like the best configuration that would cause the least lag time and most reliable wireless connection without crashing. price is not a limitation but i dont want to be wasteful considering this is soley a poker machine (no movies, downloading, etc.)

1) is Intel® Pentium M Processor 740 sufficient or upgrade to 750, 760, or 770?

2) is 512MB Dual Channel DDR2 SDRAM sufficient or upgrade to 1gig or 2gigs?

3) is ATI MOBILITY™ RADEON® X300 64MB sufficient or upgrade to 128MB ATIs™ Mobility Radeon or 256MB NVIDA® GeForce?

4) is Intel® PRO/Wireless 2200 Internal Wireless sufficient or upgrade to Intel® PRO 2915 and Dell 350 Bluetooth Internal Wireless Cards?

thanx.
