I'm sorry, but

I'm like mentaly retarded when it comes to computer parts. I recently bough Command and Conquer 3 and when I tried to play it I found at that my GPU thing sucks. I need to know what kind of GPU I should buy. I have $200 to spend on one. What graphical settings should I expect to play on with this new one?

My specs: 

Windows XP

Intel(R) Pentium(R) 4 CPU 2.66GHz

1526MB RAM

Intel(R) 82915G/GV/910GL Express Chipset Family

First

Do you have a PCI-Express slot or a AGP slot?

Is you Processor is LGA 775 (But I think its a PGA 478)

Umm, I have no idea. How do I find that out?

You have to look your motheboard.

Then tell me how many slots you have.

I think your motherboard has only 1 PCI-E slot or a AGP slot & this the first slot.(If you hav 3 slots first one is AGP or a PCI-E others were PCI slots)

You can put any PCI-Express Graphic Card to you PC but some Graphic Cars requiers higher Power

Thanks alot.
