help with graphics card upgrade


Beta member
so I've been thinking about a graphics card upgrade but i have not been able to find a card that will fit into my dell 531s and considering the power supply is only 250 watts its even harder. but recently i stumbled upon this site and it says that I'm only using about 190 watts of that excluding my current video card which is an ATI Radeon x1300 pro.

my current PC specs:
dell inspiron 531s slimline case
Intel model 0RY206 motherboard
amd athlon 64 x2 3800+ Windsor
3 GB Dual Channel 667 MHz ram
ati Radeon x1300 pro 256 MB Pci-e x16
onboard audio
cdrw/dvd combo drive

thanks in advance,
Eric D
