just as the title says. i can't fine review comparing the two. TPU did have comparison with 390 but isn't that 390 is a bit faster than 290? or did performance difference between 290 and 390 is negligible at best?
Stock 290 throttles like hell unless you're cooling it with a jet turbine. If you can get an AIB 290 that'd be better, if not then I'd suggest the 470.
