The advantages of TGX over SX?
The TGX is supported under 4.x, the SX is not. Each SX takes up a SIMM slot, which reduces the maximum amount of system memory possible, but unless you really need to max out your RAM (and if you do, you should think about upgrading) this isn’t a problem. The TGX has fractionally better performance on some 2D operations, but by and large there’s not much in it. Unless the system is running 4.x I’d choose the SX. Or, better still, dual headed with the SX *and* a TGX+.
