Advice needed upgrade graphics card or PC?

Apologies pressed retrun instead of tab! to continue:

My motherboard is an MSI K7T266mhz Athlon XP 1466mhz

Graphics card is Geforce2mx with 64mb memory.

What is the most cos effective upgrade?

Also if it is the graphics card route. My motherboard only accepts up to AGP 2.0 with1x,2x,4x. Waht would be the best graphics card I could install?

budget?

I would recommend a full upgrade to a new system.If money is a bit tight,go with AMD.You should be able to get a MOTHERBOARD,CPU,RAM,AND VIDEO CARD,for aound 600 dollars.You'll need a new POWERSUPPLY as well.But if you buy a new case,you could get one with it.However,I recommend buying a good quality PSU for reliability purposes.I say new system because your current cpu will bottleneck any of todays mid to high range AGP card,ie:1900pro,XT,8600GTS,etc...Those cards can be had for under 200 dollars,but again,your processor will hinder your gaming and video playback.Goodluck.

Thanks for your advice. Broke the bank buying the monitor so buying a new motherboard for $600 was not really an option. However, if a new graphics card will not improve performance then I may have to consider. I was looking at graphics cards costing around £50 /$100 -Geforce 7600GT?

A new video card will increase performance, what they are saying is the card won't run at maximum performance because your processor will hold it back some. An upgraded card will still run better than what you have.
