No, I usually wouldn’t advertise some random online deal, but NewEgg happens to have some crazy special on GTX 260s for only $149. With free shipping, even.
This is not a bad card to fill some of your empty PCIe slots with, and the compute/$ it offers is huge. (Think of it as this being 1/2 of a GTX295, and those go for $500 each)
No, I’m not related to NewEgg nor do I get any kind of commission. I apologize for even mentioning such a thing, but it really is an opportunity to add some cheap power to a box.
