Upgrading help

Alright so my comp is pretty old now...and I need to do some upgrading
So at the moment I have:

Intel Core 2 Duo @ 1.86
160gb maxtor hdd
450/550w PSU
Nvidia 7600GT
Crappy 17" crt...

My main concern is my monitor and graphics card/ cpu
I was checking out newegg and stumbled across this deal:
http://www.newegg.com/Product/Product.aspx...N82E16814130359

So I thought if I got that graphics card, would I need to purchase a newer CPU to maximize performance?

 

How much RAM is in the computer and where are you trying to increase performance?

 

I wouldn't upgrade your monitor if you're new graphics card doesn't have a DVI connection on it.. CRT's are still good monitors. Other then that, I don't really see a reason why you should upgrade it, I mean.. it's not really THAT bad.

 

Hey read my post for graphics cards let me find the link. Kk here it is hope it helps! http://www.sythe.org/showthread.php?t=422436


And for a card I recomend the Radeon HD2400 Pro.
