Anyway, I'll download it and see what happens.
I believe you should run it pretty smoothly.

As for barely running Minecraft. Bare in mind that Minecraft is very poorly optimized. For instance I can't run Mincraft at decent frame rate on my oldest laptop computer (1.6 GHz, 512 MB RAM).
I can run vanilla Minecraft at decent frame rate on my newer laptop computer (AMD Turion 1.8 GHz two core, 4GB RAM, Windows7 64bit) but adding some mods can lower the frame rate significantly.
And in order to run Mincraft with all those moods and having good frame rate I need to do it on my newest desktop computer with 8 core AMD CPU running at 2.0 GHz with 16 GB of ram. And even on this configuration I could cause the reduced frame rate if using to many dimensional anchors which are used to prevent unloading of certain map chunks so that machines that are placed on them still operate even if I have gone far away.
So don't judge your computer capabilities based on Minecraft.

As for broken left mouse button you might be able to fix it depending on what is the cause of its problems.
Sometimes the problem is that the plastic of the mouse button simply wears out and no longer presses on the switch as it should. In such cases I used to simply put some duct tape on the plastic in order to extend it (fill up the wored part).
Other times the switch itself might wore out. In such cases it is sometimes possible to unsolder it and switch it with ones that belongs to right or middle click buttons.
And in one case I just had to disassemble the switch itself and clean its inside components with so called "contact spray" to remove oxidation.
But on the other hand buying a new mouse isn't such a big expense. Here in Slovenia you can get decent wireless mouse for about 15 EUR or a wired mouse for as low as 8 EUR cost.
