I'm interested in buying a new PC with XP Pro that will be equipped as is, to last the next 4-5 years (I don't want to have to add "this or that" four years from now if possible, but have no desire to go too far overboard either). I currently have a four year old P4 2.80GHz with 512 MB of RAM using XP Home. It's used for trading (QT, IB, Ensign and Excel - but not all at the same time necessarily) and some general surfing, e-mail, etc.
I noticed on Dell's website that the available processors were:
Intel® Coreâ¢2 Duo Processor E6600 (4MB L2 Cache,2.4GHz,1066 FSB) [add $150 or $5/month1]
Intel® Coreâ¢2 Duo Processor E6700 (4MB L2 Cache,2.66GHz,1066 FSB) [add $350 or $11/month1]
Intel® Core⢠2 Duo Processor E4400 (2MB L2 Cache,2.0GHz,800FSB) add $0
Intel® Core⢠2 Duo Processor E6320 (4MB L2 cache,1.86GHz,1066FSB) [add $50 or $2/month1]
Intel® Core⢠2 Duo Processor E6420 (4MB L2 cache,2.13GHZ,1066FSB) [add $100 or $3/month1]
Intel® Coreâ¢2 Duo Processor E4500 (2.2GHz, 800 FSB) [Included in Price]
Which one of these choices would you recommend, and how much memory with it? And, would I notice a significant increase in speed and performance compared to my existing system (seeing that the available GHz is less, although they have the Core 2 Duo Processor)?
Thank in advance.
