Anyone have suggestions on what the best Card would be to use with an Asus M2NE Mobo / Athalon 64 combo? Right now i'm eyeing a PNY Geforce 7300GS PCI-E w/256mb. I won't really be doing any gaming, mostly graphic design and maybe PVR in the future. Is 256MB overkill or is 128MB sufficient? Trying to build a budget but quality rig that will last.
