The single most important question is what is your budget? Once we have that we can find you the best answer you can afford.
As for the card you are looking at... the owner misspelled the manufacturer's name all three times it was mentioned (not a good sign). It is a refurbished card, meaning it has no warranty beyond the initial 30 days. It may be a bargain, but it could also be a time bomb.
Since you have a 375W PSU, you will need to upgrade it to use any upper-mid to high level cards.
I currently have this card
and am very happy with it. But, again, it will depend on your budget.
