Dell Precision 450 Workstation ?

After taking every thing from my Abit VP6 , im going to leave her and going to a new Workstation i I've come to the conclusion to take a dell

im going with the Dell Precision 450 here are the specifications:

Processor : Intel Xeon 2.2 GHz
Chipset : Intel E7505
Installed Memory : 1 GB (DDR SDRAM)
Operating System : Microsoft Windows XP Professional
Hard Drive Capacity : 120 GB
Installed RAM 1 GB
Recommended Use : Corporate Business, Small Business


i want this machine to be with me as long as 7 to 9 years, will this be good for that or i need to do some changes in it

the Processor, Memory, Hard Drive are good i think you will early crry this rig for more then 7 years if you are a gamer i will suggest you to put a GeForce 7800 GTX you will get a Extreme Graphics Performance from this

im not a regular gamer i just want this pc for my work basics thats it , i want a good performance from this thanks for replying secrecy
