The use of a DSP accelerator card in modern PC-s is not really justified as the processing power is nowhere near of what the CPU can provide. I think of this card more as a dongle for the plugins. The plugins are nice but they are still only plugins and while plugins got some advantages they aren't the real deal. UAD does not offer upgrade options for users of older plugin versions which means you have to repurchase the same hardware emulation over and over as they "improve" a bit, which is odd because they sold it in the first place as authentic recreation of classic hardware. So beware the UAD platform is a ripoff machine.
