Advice Buying Used TDM Cards

Those of you considering building a TDM Rig, make sure you buy as many core cards as the system you are attempting to build. If an HD2, then get two core cards, vs a core and an accel. This way if your core goes bad, you keep going as a core card can be a core card and/or an accel card.

You can have an HD3 that consists of three core cards. Considering the used price variance is negligible it makes sense!
