I am noob to computer gaming and I did my first build 6 months ago. Long story short I got a Gigabyte 560 ti 448 and planned on getting another one eventually to SLI. The day the 660 ti came out I thought my card would go cheap, but instead it is discontinued. Is this the norm for non-reference cards? Is there anywhere to buy discontinued cards?
Sorry if this is a dumb question.
