Well first off, there's no such CPU as a T9100. You may mean a derivative around there. Even still, that class of Intel CPUs came out around 2008. So for Dolphin, they're going to be slow. And the 8700m is an old and slow card. Don't expect manygraphical enhancement.
The computer with the 1090T will perform better than the laptop. The CPU is stronger in terms of single-core performance (what Dolphin needs), and the GPU is way stronger (but it will only use one of the cards, there's no SLI support)
There's no such thing as a Xeon 5360. Do you mean the Xeon X5365? It should perform about the same as the 1090T. The GPU is a bit weaker, so you won't be able to raise the enhancements as much.
The Xeon 5310 is weaker then both of the other desktops
