My nVidia GeForce 8400 GS has stopped working. I am considering buying a new one and I struck between AMD and nVidia. I've somehow convinced myself to go back to nVidia and have now narrowed down to one particular model, GT630. Is that okay to use on my motherboard D61WW? And are there any other GFX cards that I can go for or is GT630 the best for my budget which is around $85-$90. Thank you in advance.
