keep in mind wotlk is more demanding on your PC than current WoW, patch 3.0 may be a good indicator of how many your PC can handle.
It should be noted that you can set the beta client's graphics settings such that you end up with the exact same graphics performance as your main/live client. I've tried it and I can get 'em to where they look almost identical and get within 1-2 FPS of each other. Now, where I will agree is with memory usage. The couple of times I checked, in the same zone, the beta client was using about 30% more memory (700mb vs 500mb). That aspect will probably affect single-machine boxers with 4GB of RAM more than any other aspect of things.
