Go with E4500

Before that, which RAM you have (DDR, DDR2 ........)

Also which motherboard you have ?

Go to a Computer Shop & you can buy those parts.

For you memory, which memory type you have? (DDR, DDR2 .....)

I guess you have DDR

& your graphic card is AGP. You will have to buy a good AGP graphic card.(Not PCI-Express)

X1950Pro (AGP)is a good card for money as well as 7900GS (AGP)

Cooler Master Centurion 5 Blue

You will run them in Dual Channel without a problem.

You should wait for G9xxx graphic card like your your Dealer said.

120 Extreme is very good.

If I were you I will get Antec 900.

For the monitor, 22" Wide Screen monitor

Yo man.

Before that try to upgrade your processor
