This has nothing to do with video cards and most likely not system RAM.

When a G8 figure, or character, is loaded, all the applicable morphs load with it. The more morphs installed, the longer the figure takes to load into the scene.

However, in the case of the OP, they appear to have a bad morph or G8 install. Checking the log file would help in finding where the load is failing. The load of the G8 figure has very little to do with system RAM or system specs.
