Pam...Can anyone tell me which is right?

I haven't been able to get back on SL for a few weeks now. Turns out I need a new
graphics card. I am so lost with this since there are so many model numbers and series..etc...

I found two that might be right. Can anyone tell me if either of these are good or have problems.

nVidia GeForce 8500GT 8500 GT 1024MB 1GB DDR2 PCI-E 16X 128bit Video Card VGA/DVI/CRT/TV-out


HIS H925H256RPN-R Radeon 9250 256MB (128bit) DDR PCI DVI & TV


I have windows xp and just bought a new hardrive. A western dig
WD Caviar 16E 500 sata

I don't want to buy something that won't work then I have to fight to do a return

THanks
Pam
